Full Arch Rubber Dam for Restorative Procedures

By Dr. Bikini Calvin Klein Calvin Klein Ropa Interior Hombre Christopher C.K. Ho

The application of rubber dam is recommended to achieve adequate isolation for many dental procedures, helping to provide a clean, dry environment and minimises contamination from saliva and blood.

It also plays a crucial role in preventing ingestion or aspiration of instruments, tooth debris, dental materials, medicaments, irrigants or other foreign bodies. As well as the provision of isolation and moisture control, there is the added benefit of retraction of lips, cheeks and tongue. Calvin Klein Tanga This allows improved access, visualisation and protection of soft tissues from rotary instrumentation. The use of coloured rubber dam helps to achieve better visualisation of the teeth with a contrasting colour of the rubber dam material.

It is often commented that placement of the rubber dam is a difficult procedure and that the time it takes to apply the dam is excessive. Boxer Calvin Klein Mujer Slip Calvin Klein Baratos The other concern for dentists is that it can uncomfortable for the patient while the dam is being placed due to the stretching required to seat the dam.

The author utilises a technique that has been very useful in his practice in isolating a full arch very quickly, and comfortably for the patient. This is particularly useful when working on multiple teeth with direct procedures like the removal of amalgam and caries, and placement of restorations. It can also be effectively used in the preparation and cementation of indirect restorations, e.g. Calvin Klein Bragas porcelain veneers/onlays/crowns.

This technique is a useful one to have in your armamentarium for utilisation within clinical practice.

Sonic activated composite in a full arch build-up for extensive tooth wear

Extensive multi-surface tooth wear is common in several people and your Sydney dentist will explain how it may easily be caused by a different things:

  • Chemical erosion. When there is acid regurgitation or the presence of a naturally acidic oral environment, the teeth may be severely worn away so that the bite collapses as teeth height is reduced on the maxillary and mandibular jaw.
  • Bruxism. Calvin Klein Boxer Hombre Night grinding or bruxism is a paroxysmal habit observed during night slumber, but may also be experienced in the day. It is an involuntary problem that involves the over-clenching of the teeth that often leads to wear facets and damage.
  • Malocclusion. Boxer Calvin Klein Outlet When the patient’s bite is wrong or is misaligned, this disharmony can cause damage to the teeth. Calvin Klein Underwear España This is common with people with cross-bite, deep bite and edge-to-edge bite. The upper and the lower teeth contact each other, in damaging fashion so that teeth become excessively worn away.
  • Ideally, this issue is resolved by installing dental crowns and bridges on all the teeth to restore the bite and the appearance of the teeth. Boxer Calvin Klein Mujer This would be acceptable when not much damage has been incurred but when very little tooth surface is left to work with, retention for the prosthetics is highly compromised.

    Dr. Chris Ho follows a different approach and it is explained in detail in the attached post. In lieu of invasive and expensive crowns, composite resin is provided to restore the worn teeth. Utilizing a template, a specialized bonding adhesive and reinforced composite resin, the patient is given a better reason to smile.

    Advantages of getting a sonic-activated composite full-arch build-up:

    • It involves a less invasive and more conservative approach.

3M True Definition Scanner – the way of the future with Digital impressions

smallest camera with 3D technology

3M True Definition Scanner

The CAD CAM technology has brought amazing contributions to various industries and in Dentistry, Computer Aided Design, Computer Aided Manufacturing is offered in the form of CEREC, (Chairside Economical Restoration of Esthetic Ceramics). Through the CAD CAM, digital technology is conveniently and practically utilized to provide patients with a better treatment option. Removing the laboratory technician from the picture, ceramic restorations (be it crowns, veneers or fillings) are fabricated by the Sydney dentist using a machine and are delivered to the patient, on the same day.

CAD CAM CEREC is definitely impressive. Those who are able to afford it can enjoy its amazing features, but it really still remains to be costly—enter 3M True Definition Scanner, 3M’s answer to the expensive digital diagnostic technology. Especially with the developments with this technology, coming in the following years, you can expect so much more from it.

  1. Precision. Digital technology allows perfect recording of detail that no other impression material can exactly manufacture. A lot of discrepancy occur with the use of rubber impression materials—and a lot of things are at play here. The digital picture produces accurate models that will aid in the success of the overall treatment process.
  2. Ease. Boxer Calvin Klein Baratos On the side of the patient, going digital will mean no mess and hassle-free cast fabrications. Dental impressions can be quite uncomfortable. The trays are forced into the mouth along with the rubbery material and it often brings the patient to gag. Digital imaging removes the need for this. Records and models are created easily.
  3. Collaboration. With the technology, users enjoy a cloud-based system of collaboration between the dentist, laboratory and others. This makes diagnosis and fabrication so much easier.
  4. Today there are already several machines available, but the 3M True Definition Scanner is the one that has the smallest camera with 3D video capability. Tangas Calvin Klein Baratos Through this technology, dentists are able to capture and simultaneously view a true replica of the oral anatomy.

    There remains some discrepancy with the workflow, however, but I remain hopeful that things will be resolved eventually. Today, it still takes a few days for actual models to be fabricated, which poses the inquiry of whether or not such models are actually necessary. “Do we really need models?” – if the machine is so accurate we may be able to be “model-less” for the simple cases.

Ceramic restorations on Discoloured stumps around the gingival tissues

A tooth can discolour for a lot of reasons. If you ask a Sydney dentist about this, you will be advised that teeth could discolour due to age, food, beverage, medications, trauma, dental caries or exposure to highly staining compounds.

A tooth fitted with a porcelain fused to metal crown may stain after prolonged exposure to the metal. This results in an unsightly discoloured stump that often reflects and affects the gum tissue. Teeth with discoloured stumps are very unattractive. Boxer Calvin Klein It gives the patient a smile that looks dirty, old and diseased, especially since the stained appearance reflects on the soft tissue or gums too.

It is a frustrating problem because even if you place the margins at a subgingival level, the problem still remains. When we encounter a problem like this in the clinic, we suggest a few things to the patient:

1. Calvin Klein Boxer Internal bleaching. An initial remedy for the discoloured stump that has spread to the gingival tissues is to perform an internal bleaching procedure. This is most appropriate for root canal treated teeth, with effectiveness that is quite unreliable.

2. Opaque restoration. A more definite solution that we provide involves masking or covering the discoloured stump with an opaque restorative material or composite resin. Using Kolor +- Kerr Dental we overlay the darkened area to mask the unappealing area so that it does not reflect on the crowns and on the gum tissues.

This kind of remedy is applicable for root canal treated teeth, teeth receiving dental crowns, bridges and veneers. It may be performed on porcelain-fused-to-metal crowns, all-porcelain crowns or even zirconium crowns. Boxer Calvin Klein Mujer The result you receive is a natural-looking teeth restoration, the appears good as new.

Class II: Wedge doesn’t do anything!

Dental caries or defects on the teeth may occur on different areas. Calvin Klein Ropa Interior Mujer Barata Pit and fissure caries affect the occlusal table and decay of this nature is limited to just one surface, but when caries extend to the proximal areas, a different approach is required. When the sides are involved, a barrier or matrix band is utilised to keep saliva and blood away from the area and properly restore the proximal and contact points. Bikinis Calvin Klein Baratos Ideally, a matrix barrier should be enough. It is inserted in between the teeth, is held in place with the help of wedge and the restoration is given to the tooth without any problem.

Unfortunately, sometimes you will come across those frustrating cases when you stick a wedge into a matrix and the bloody gum still bleeds as you work. This can be quite frustrating because it makes it hopeless to restore the tooth. Calvin Klein Bañadores The blood and saliva will disrupt your work, so you will take longer. Calzoncillos Calvin Klein Hombre Calvin Klein Slip Either that or the restorative work you complete will be poor.

One way of adapting the matrix more intimately is the use of another wedge (two wedges) or another neat trick is to use Teflon tape (aka plumbers tape) to adapt the matrix to ensure a clean field to place your composite. Comprar Bikini Calvin Klein Using a Teflon tape is unusual but it offers a few benefits:

  • Teflon tape will isolate the and provide visual enhancement for results achieved. With its help, the dentist is able to shape the composite up to the proximal third of the crown.
  • The Teflon tape is very flexible and thin.

USEFUL APPS FOR DENTISTS AND PATIENTS

The world as we knew it has changed. We are in the digital age and to better survive, one has to fully integrate the changes into their lives. Calzoncillos Boxer Baratos The same could be said with dentists. These days, we have multiple technologies in our grasp, and one of the easiest for patients to understand is using a tablet like an iPad. Bañadores Calvin Klein Hombre Baratos Slip Calvin Klein Being able to demonstrate images on a tablet is just so much more high tech for a patient. This sets you apart from another Sydney dentist and helps educate your patients in a more effective manner.

Here are just some apps for dentists and patients:

The centripital layered build-up of a posterior direct composite resin

No matter how brilliant the Sydney dentist is, did you know that all composite restorations face as much as 5% polymerized shrinkage?

This phenomenon lead to:

  • Internal debonding and the inevitable dislodgement of the restoration.
  • Marginal openings that causes leaks and re-infection or recurrence.
  • Cuspal flexure and microfractures which causes consequent permanent deformation due to the load subjected by the restorative material.
  • Postoperative sensitivity that may be the result of tissue exposure due to microleakage.
  • Marginal staining, also caused by microleakage.
  • In the clinic, I make use of nanofilled composites to remedy these noted discrepancies with hybrid composites. Boxer Calvin Klein Nanofilled restorative materials have particles that are as minute as 0.02 microns. With this, restorations are more successful, with recorded shrinkage as low as 1.6%. More so, it allows the dentist to create better restorations.

    The article below does not only count the number of benefits one can enjoy with nanofilled composites. It also discusses the importance of proper manipulation and layering. This technique involves the incremental addition of restorative material into a cavity. Calvin Klein Tanga Instead of packing a bulk of composite into the tooth, the filling is brought in, little by little, in a technique called “layering”. With the use of a nanofilled composite, you already improve success rates; when you perform the layering technique, you increase polymerization depths, improve aesthetic results and decrease polymerization stress.

    This follows a precise process:

    Step 1: Shade selection. To ensure aesthetic satisfaction, proper shade is selected.

    Step 2: Rubber dam placement. Proper isolation of tooth is performed to improve results.

    Step 3: Preparation. Tooth is drilled to remove diseased tissue and to prepare it to receive the filling material.

    Step 4: Etching. Application of the etchant prepares the tooth to receive the bonding material. Successful etching improves success.

    Step 5: Internal Adaptation. Boxer Calvin Klein Outlet Making use of flowable composite that better penetrates the tissues.

    Step 6: Incremental Layering. Calzoncillos CK Baratos Composite resin is added in small amounts.

    Step 7: Building the Proximal Contact. Ropa Interior Calvin Klein Madrid If the restoration involves the proximal areas, the proximal contacts should be restored harmoniously.

    Step 8: Building the Artificial Dentin. Dentin composite is placed in the right shade.

    Step 9: Building enamel layer. Enamel composite is then provided in the right shade.

    Step 10: Occlusal staining. Whether you like it or not, it is done to satisfy aesthetic appeal.

    Step 11: Finishing and Polishing. The tooth is moulded and polished to mimic the appearance of the natural tooth.

    Step 12: Rebonding.

Geistlich Mucograft ® Seal

Depending on the case presented to the Sydney dentist, there will be instances when the needs of the patient will go beyond what is usually done, just so health, function and aesthetics could be restored.

Mucograft seal is collagen membrane matrix that may be applied to the patient’s mouth. Calvin Klein Boxer Hombre Calvin Klein Underwear Mujer It is a synthetically fabricated material made from purified type 1 collagen so that it can guide, promote and hasten tissue healing for the following cases:

  • Difficult tooth extraction that involved extreme bone loss, such as in the case of impacted teeth removal.
  • Dental implant placement procedures on areas with insufficient bone. When diagnostic evidence reveals poor bone level and quality, it could be improved with bone grafts and matrices.
  • Immediate loading of dental implants following a tooth extraction to gain proper stability.
  • Tissue replacement after removal of bony defect or pathology, when gum tissue has been lost from the surgery.
  • Ridge augmentation procedures for cosmetic or treatment purposes, either for removal dentures or dental implant placement.
  • Soft tissue grafting procedures as a result of gum recession or disease, to successfully cover exposed tooth or bone.
  • Sinus lifting procedure for treatment purposes.
  • After the procedure, after the grafting material is placed the tissue soft tissue is brought back and to enhance healing and success. Tangas Calvin Klein Baratos Calzoncillos CK Baratos Behaving as a soft tissue covering or dressing, the collagen material is placed, sometimes to hold the bone graft.

    The people at Geistlich have produced a new collagen matrix named Mucograft ® Seal. It comes in a convenient circular shape and is indicated for the sealing of extraction sockets with preserved buccal walls in combination with Geistlich Bio-Oss ® Collagen in Ridge Preservation procedures. Tanga Calvin Klein Mujer Calvin Klein Slip The collagen matrix allows predictable soft tissue dimensions and provides an alternative to soft-tissue grafts.
