Today’s periodontists are extensively trained in surgical procedures to treat and maintain patients with edentulous or partially edentulous arches, integrating endosseous implants into periodontal therapy.
Surveys And Studies
Oral health surveys indicate there are significant numbers of individuals with compromised dentitions for whom endosseous dental implants may be indicated.
In many circumstances, implants are an alternative to fixed or removable prosthetic appliances.
The success of implants has been attributed to their firm bone anchorage, referred to as osseointegration, or functional ankylosis.
Initial studies focused on commercially pure titanium implants with a relatively smooth surface created by the machining process.
Subsequent investigations indicate implants made of titanium alloy and/or with relatively rougher surfaces also become integrated with bone.
These include, but are not limited to, titanium plasma sprayed, acid-etched, grit blasted acid-etched, and hydroxyapatite coated implants.
The bonding of hydroxyapatite to bone differs from titanium and has been termed biointegration, which denotes a direct biochemical bond of the bone to the surface of an implant at the electron microscopic level and is independent of any mechanical interlocking mechanism.
Several kinds of dental implant systems are available, classified according to their shape and relation to the bony housing. They include subperiosteal, transosteal, and endosseous implants.
The most frequently used implants are endosseous implants which include a range of sizes, shapes, coatings, and prosthetic components.
Implant length and width can be chosen to fit the available bone and prosthetic components can be selected in a size and angle to accommodate the final restoration.
Appropriate Shape Selection
The selection of implant shape involves the exercise of professional judgement, taking into account such factors as available bone quality and the dimensions of the edentulous ridge.
A threaded implant may provide additional immediate fixation compared to cylindrical implants as a screw-type implant has more surface area for bonding than a parallel walled press-fit implant.
The implant surface further affects the long-term fixation and stabilization of the implant. A porous coating on an implant can achieve more bone contact per implant length than an implant with a machined titanium surface.
Other surface modifications of implants include a roughened surface (i.e., grit-blasted, or grit-blasted and acid-etched), microgrooved or plasma-sprayed titanium, and plasma-sprayed hydroxyapatite coatings.
