Implant Placement

Implant Placement After the desired depth and diameter of the recipient site  is accomplished, the implant is placed. For titaniumimplants, an uncontaminated surface oxide layer is necessary to obtain osseointegration. Contamination, by touching the implant with instruments made of a dissimilar metal or by contact with cloth, soft tissue, or even surgical gloves may affect the degree of osseointegration. HA-co

Preparation of Implant Site

Preparation of Implant Site After the bone is exposed the surgrcal guide template is positioned, and a periodontal probe is used to make a FIG. 14-46 Kazanjian style of vestibuloplasty allows access for implant placement and increased“vestibular depth and attached tissue, as well. FIG. 14-47 Access is gained to bone, and periodontal probe isplaced through guide hole of splint and locates ideal implantpositio

Surgical Guide Template

Surgical Guide Template The coordination of the surgical and prosthetic ~edures through proper treatment planning is one of the most critical factors in obtaining an ideal esthetic: and functional result for the implant restoration. The surgical guide template is a critical factor for implants placed in an esthetic area, because even slight variations of angulation can have large effects on the appearance of t

Informed Consent

Informed Consent Once adequate information is obtained to allow formulation of a treatment plan, informed consent is obtained before surgery. This step is best accomplished using a team approach involving the surgeon and the restorative dentist. Models of various implant-supported prostheses can be used to demonstrate the proposed treatment. The patient should be informed regarding the timing of surgery, the

Evaluation of Implant Site

Evaluation of Implant Site  Evaluation of the planned site begins with a thorough clinical examination. Visual inspection and palpation ‘will allow the detection of flabby excess tissue, narrow bony ridges, and sharp underlying ridges and undercuts that may limit implant placement. Clinical inspection alone may not be adequate if the thick overlying soft tissue is dense, immobile, fibrous tissue (Fig. 1


SURGICAL PHASE TREATMENT PLANNING Clinical’ and radio graphic evaluation of the planned implant site is essential to treatment planning, to determine whether adequate bone exists and to evaluate the BOX 14-5 Contra indications to implant Placement (NIH Consensus Conference) • Acute illness • Terminal illness • Pregnancy • Uncontrolled metabolic disease • Tumoricidal radiation to the implant site


PREOPERATIVE MEDICAL EVALUATION  OF IMPLANT PATIENT As with any surgery, the implant patient must be assessed preoperatively to evaluate patient ability to tolerate the proposed procedure. The predictable risk and the expect- . ed benefit should be weighed for each patient. Surgical . placement of dental implants may be associated with certain risks. – , One ‘Set of concerns is, tlle’ Immedia


IMPLANT PROSTHETIC OPTIONS  Completely Edentulous Patients At least three prosthetic implant options exist for the  completely edentulous patient: They include (1) theimplant-‘ and tissue-supported overdenture, (2) the all implant-supported overdenture, and (3) the complete implant-supported fixed rehabilitation. II11P”lIIt· (/1/(1 tissue-supported overdcnture, Completely edentulous patients have


CLINICAL IMPLANT COMPONENTS Two-stage osseointegrated implants are generally designed to support screw-retained implant restorations. These twostage implant systems offer many advantages over conventional dental restorations and one-stage implant systems (Box 14-3). Fabrication of screw-retained implantrestorations requires the use of several component parts that heretofore had not been routinely described in

Biomechanical Factors Affecting Long-Term Implant Success

Biomechanical Factors Affecting Long-Term Implant Success Bone resorption around dental implants can be caused by premature loading or repeated overloading. Vertical orangular bone loss is usually characteristic of bone tion caused by occlusal trauma. When pressure from traumatic occlusion is concentrated, bone resorption occurs by osteoclastic activity. In the natural dentition, bone reposition would typical
