The role of the restorative dentist in the diagnostic and maintenance phases of implant therapy--Part I: Patient selection.

The objective of patient selection is to ensure that the patient's need and desire for dental treatment is consistent with the clinical findings and the clinician's ability to provide treatment. Considerable effort is required to gather and analyze the data necessary to determine whether implant therapy is feasible. Additional planning is required to determine if this is the best treatment modality. All aspects of dental treatment need to be considered and planned before the implant phase of treatment is contemplated. Our experience indicates that the potential need, and indeed necessity, for conventional dental treatment in patients seeking implant therapy is high. The general practitioner is the logical resource to fulfil the dental needs of the majority of these patients.

The role of the restorative dentist in the diagnosis and maintenance phases of implant therapy--Part II: Prosthetic planning.

Prosthetic planning is critical to the success of the diagnostic phase of implant therapy and is used to establish fixture numbers, position and the optimal occlusal scheme, based on the design of the definitive prosthesis. The prosthetic needs of the patient, anticipated functional and parafunctional forces, restoration fabrication and serviceability are all considered. A clear picture of the intended rehabilitation is provided to the surgical team and expedites the consultation between implant team members. Comprehensive diagnostic planning using mounted diagnostic casts and diagnostic wax-ups will provide definite parameters for fixture number, position and alignment, and permit the fabrication of radiographic and surgical templates as the treatment sequence progresses. Patients need to be informed of the time and expense involved in the diagnostic phase of implant therapy prior to the initiation of the planning process. The practitioner conducting the selection and planning phase is entitled and should expect financial remuneration commensurate with the time and effort required to achieve the objectives of this phase of implant therapy. The Planning Process Using mounted diagnostic casts and diagnostic wax-ups: 1. Establish fixture numbers and position; 2. Establish the optimal occlusal scheme; 3. Design the definitive prosthesis; 4. Fabricate a surgical template. Design Principles--Summary 1. The location and number of fixtures dictates the prosthetic design and influences restorative success. 2. A restoration must be designed to distribute forces to the fixtures without overloading the bone, and therefore be able to withstand anticipated functional and parafunctional loading. 3. Design for optimal function and esthetics with a regard for patient comfort and maintenance.

The role of the restorative dentist in the diagnosis and maintenance phases of implant therapy--Part III: The restoration and maintenance of oral health prior to the provision of the implant prosthesis.

Establishing and maintaining the patient's oral health prior to provision of the definitive implant restoration is the responsibility of the restorative dentist and is an important aspect of comprehensive treatment. The additional time and expense required to provide oral hygiene and conventional dental treatment needs to be acknowledged by the implant team and the patient. An anticipated three to five treatment hours are often required to provide maintenance and hygiene care, with additional time needed to provide individualized conventional dental treatment to each patient. The provision of implant therapy is a rewarding experience when all aspects of treatment are properly planned and competently performed. The general practitioner is the logical resource to provide much of the necessary treatment that is directly and indirectly related to the provision of implant restorative dentistry.

A progressive treatment protocol for maintaining tissue associated with implants.

This article presents a protocol for the management of the soft and hard tissues surrounding implant-supported prostheses. Treatment requires an evaluation of soft tissues as well as a radiographic interpretation of the hard tissues associated with peri-implant degeneration. As the degree of soft and hard tissue degeneration increases, treatment must become more aggressive. A classification is outlined for diagnostic criteria and appropriate treatment.

Direct assembly of implant suprastructures.

The technique described uses innovative technology and conventional prosthodontic techniques to directly assemble a cast framework to implant abutments with a resin luting agent. This technique has been used to restore multiple implants with a fixed restoration and for implant connecting bars to support overdentures. Brånemark and Calcitek implant systems have been used successfully.

Denture adhesives--pH and buffering capacity.

Aqueous solutions of some denture adhesives will produce a pH below the critical pH of hydroxyapatite. This article measured the pH of selected denture adhesives. The pH and buffering capacity were established for 10 readily available denture adhesives. The pH was determined from samples in dilutions of 1:10, 1:20, 1:30, and 1:40 denture adhesive to deionized water. A glass pH electrode coupled to a pH meter was used for pH determination. Six of the 10 denture adhesives tested had pH values below the critical pH of hydroxyapatite. This pH was maintained for the 2-hour duration of the testing. Prolonged contact of denture adhesive and tooth substances may dissolve hydroxyapatite crystals. Samples of denture adhesives to determine buffering capacity were prepared in a ratio of 1:20 by weight of denture adhesive to deionized water. Another series of samples was prepared in a ratio of 1:20 by weight of adhesive to freshly cannulated submandibular saliva. The pH was determined at the 24-hour time interval. Samples were then titrated with 0.1N sodium hydroxide solution in the presence of phenolphthalein. The same denture adhesives demonstrated low pH values at the 2-hour and 24-hour time intervals. These samples tended to be well buffered. It is recommended that denture adhesives with low pH values not be used in an environment with natural teeth or remnants of natural teeth.

Some advances in endosseous implants.

A major advance in endosseous implantology hinges on the coating of titanium implants by porous biodegradable, bioreactive tricalcium phosphate ceramic. When implanted into alveolar bone by a careful technique, the ceramic is resorbed to be replaced by bone. As a result, the endosseous implant becomes ankylosed to the bone. This represents a stable implant/bone interface as opposed to the unstable connective tissue interface that encapsulates many other implant devices.

Prosthodontics--Past, present, and future.

1. The geographic areas served by licensed dental mechanics will increase in number and size in the future. 2. There will be increasing difficulties in supplying dental graduates of a high caliber from our faculties of dentistry to serve adequately in the field of prosthodontics. 3. More graduate (postdoctoral) programs will be needed to train dentists to treat difficult prosthetic patients. The need for prosthetic services is still with us and will continue to grow. Only with progressive thought and aggressive action can organized prosthodontics go forward to meet its challenges. A battle is not won on defense alone, for such has been the game plan to date. Currently, dentists have a reasonable way to deliver an important health service to the population at large. However, only with a rapid advancement in the concept of delivery of total prosthodontic care can the best interests of the public be maintained. Finally, the highest standards of practice and ethics must be the guiding principles to any future changes in the delivery of prosthodontic services to the public.
