What is a Dental Implant Exactly? • A dental implant is an ar@ficial tooth root that is placed into a
pa@ent’s jaw to hold a replacement tooth or bridge. • Dental implants may be an op@on for people who have lost a
tooth or teeth due to periodontal disease, an injury, or some other reason.

Procedure • Step One: Diagnosis: A panoral is an X-‐ray taken of the
pa@ent’s head, which shows the bones of your face from the eyes to the chin, on a flat film.
• Small metal balls are placed in the area of the planned implant as a reference point before the X-‐ray is taken. This will indicate the density in the area of the implant.

Procedure Con@nued
• Step two: – An incision is made in the gum with a scalpel. – A series of drills are used to prepare the site in the jawbone for placement of the implant.
– The implant is placed into the socket in the jawbone.

Procedure Con@nued
• Once the implant is in the final posi@on, a sealing screw is placed.
• The gum @ssue is sutured over the implant and healing is allowed for about four months before the crown is aRached.

The Prosthe@c Crown
• The most commonly used materials for ar@ficial teeth today are porcelain and acrylic.
• Acrylic teeth contain polymethyl methacrylate (PMMA) resin which forms its basic ingredient. PMMA resins are tough plas@cs.
• These teeth have greater fracture toughness than porcelain teeth.

Acrylic Teeth Vs. Porcelain
• Both acrylic and porcelain teeth can be made to give a natural appearance.
• Acrylic resists wear and tear of jaw movements. – Long las@ng
• Porcelain is stain resistant whereas acrylic is not.

Results
• Dental implant success rates well above 90% for most implant pa@ents. Similarly, long-‐term success rates are in the high 90% range and are likewise improving.

Disadvantages
• Range from about $3,000 to $4,500. • Insurance usually par@ally covers these prosthesis or may not cover them at all.
• Can get very expensive if the pa@ent needs more than one.
