Treatment Options

Implant Dentures




Crowns and Bridges

Implant Dentures

Implant Dentures

Implant dentures are used to replace multiple teeth when one does not want to worry about the movement of a conventional partial or complete denture. The implants may be used to support a denture or retain a complete denture. An implant supported denture will be locked into the implants for better chewing and confidence but still remain removable for the ease of cleaning. The implant retained denture is screwed into multiple implants and may only be removed by your dentist. Implant denture teeth are personally positioned to best fit your esthetic and functional needs.

dental implant abutment crown


An implant fixture is a root shaped titanium alloy used to replace a missing tooth or multiple teeth. An implant fixture is surgically placed in the bone of your jaw. The implant fixture will be sized to fit your missing tooth/teeth accordingly and a surgical guide fabricated to precisely place your implant fixture. Following the surgical placement of the implant(s) and an appropriate healing period; the process to fabricate and custom fit a crown, bridge, or an implant anchored or supported denture will occur. This is a rapidly evolving treatment option that has become predictable and reliable.



If you have lost or are losing your teeth a denture may be fabricated in place of implant dentures. Dentures are made of a reinforced resin which may incorporate metal for additional support. Dentures may be partial or complete in the replacement of your teeth and may be immediately inserted upon the removal of your teeth. Each restoration is custom-fitted to your mouth to help you maintain a natural smile. Your denture teeth will be personally positioned to best fit your esthetic demands, functional needs, and to help you enunciate words.

Veneer Bonding

Veneers and Bonding

Esthetic/Cosmetic veneers are very thin shells of custom shaped porcelain that are bonded/glued onto the front surfaces of teeth to correct for minor tooth rotations, misalignments, discolorations, chips, fractures, spaces, and misshapes. They are fabricated to specially fit your teeth, often strengthening weekend teeth. They may be used to match existing natural teeth or to enhance a smile providing a great conservative treatment. Veneers may be used as an alternative to bonding tooth colored filling material as the optical properties of veneers are more life like, more color stable, stronger, and longer lasting. Veneers may be used as a more conservative alternative to crowns in proper circumstances.

Dental restoration bridge

Crowns and Bridges

Esthetic crowns or caps are restorations made of gold, porcelain fused to gold, or all-porcelain materials covering the entire surface of a tooth. They are used to strengthen severely weakened or worn teeth, correct bad bites, increase tooth durability, or restore missing teeth when used in conjunction with implants or partial dentures. A bridge is similar to a crown in the design, material, and purpose. Teeth prepared for a bridge are comparable in shape to those of a crown but differ in that a bridge is used to span a space where a tooth or teeth are missing. The pontic or “false” tooth is fused to the adjacent crowns filling the space where the tooth/teeth are missing. Both crowns and bridges are cemented into place and are not removable. They are the treatment of choice for major tooth rotations, misalignments, discolorations, chips, fractures, spaces, and misshapes.
