Human histologic evidence of integration of functionally loaded hydroxyapatite-coated implants placed simultaneously with sinus augmentation: a case report 2 1/2 years postplacement.

This article histologically and clinically presents a case report showing two retrieved implants that were placed simultaneously at the time of the antral augmentation. These implants were retrieved 2.5 years after placement and 2 years after loading. To our knowledge, this is the first human histological case report of implants that were simultaneously placed with a sinus lift and loaded.

Fitting and securing abutments to implant heads: technical note.

Access and visualization in the implant-abutment area are often compromised. Tissue impingement and lack of abutment position verification may result in inaccurate fit.

Simplified implant dentistry for the restorative dentist: integrating the team approach.

In implant-supported restorations, the anticipated prosthesis determines the implant placement and angulation, therefore, the process of restorative treatment should begin at the time of surgical implant placement. This paper presents the implementation procedure of a forthcoming design modification of an implant system, developed to achieve the optional restorative objectives while maintaining the long-term success rates. First impressions are taken at the time of implant placement, resulting in more time for the laboratory, less chair-side time, and fewer radiographic verifications, while enhancing provisional and final aesthetic results for the patient.

Advanced surgical techniques in implant dentistry: contemporary applications of early techniques.

Early techniques in implant dentistry utilized immediate impression-taking and loading of endosseous implants. Because these techniques became associated with an unacceptably high incidence of complications and failures in early implant dentistry, many dental professionals came to look upon the procedures with disfavor. This disregard overlooked the fact that in many cases the utilization of immediate impression-taking and loading was successful. This presentation suggests to the clinicians to reconsider the issue of immediate loading from two contemporary perspectives. First, the author's research indicates that the benefits of single-stage implant treatment can be realized with a two-stage implant. Second, even when single-stage treatment is not elected, the advantages of faster, more convenient (and therefore more acceptable) treatment for the patient can be realized by taking an impression at the time of implant placement with the use of a new insertion tool/impression pin currently in clinical trials and described in this paper.

Sinus lift grafts and endosseous implants. Treatment of the atrophic posterior maxilla.

Patients from multicenters were treated with sinus lift graft operations and placement of implants. Surgical procedures healed uneventfully with minimum pain, swelling, or morbidity. Grafts healed with few complications or failures. Implants placed into the grafts support prosthetic reconstruction and are predictable over time. The question of what graft material to use is discussed. Grafts of non-resorbable HA (Interpore 200), bovine cortical HA (Bio-Oss), resorbable HA (OsteoGen), and freeze-dried demineralized bone powder and granules are presented. Results of biopsy, histometry, backscattered electron microscopy, cell labeling, and special stain suggest consistent bone growth into a variety of graft materials. In the authors' opinion investigation must continue to 1. Determine the healing time for different graft materials. At present, anecdotal evidence suggests that sinus grafts of autogenous bone heal for 4 to 6 months; freeze-dried demineralized bone heals for 12 to 16 months; and alloplastic materials with freeze-dried demineralized bone heal for 9 to 11 months. 2. Evaluate histologic evidence of bone growth into different bone replacement graft materials. 3. Evaluate the long-term follow-up and success of implants placed within sinus grafts. 4. Determine the remodeling potential of different hard tissue graft materials under implant functional loads.
