Evisceration with primary Implant Placement in patients with endophthalmitis.
Ophthalmology, 2007Co-Authors: Hatem A. Tawfik, Hamida BudinAbstract:Purpose To assess the feasibility of evisceration with primary Implant Placement in patients with endophthalmitis. Design Pilot retrospective study. Participants Sixty-seven patients with endophthalmitis. Methods A retrospective study was conducted to review the files of 67 patients with endophthalmitis who underwent evisceration with primary Implant Placement over an 8-year period. These patients' files were reviewed to evaluate the following: persistent infection and inflammation, spread of infection to contiguous or remote sites, Implant exposure or extrusion, and successful fitting of the prosthesis. Main Outcome Measures Quiescence of the infection, complete healing of the socket, and long-term retention of the Implant. Results Sixty-three patients successfully retained their primary Implant with rapid resolution of infection and inflammation. In 1 patient, attempts at Implant Placement were abandoned during surgery because of marked scleral necrosis. Delayed Implant extrusion was noted in 2 patients, 10 and 12 days after surgery, respectively. In 1 diabetic patient, an orbital abscess developed that was evacuated with Implant exchange. In a fourth patient, marked conjunctival prolapse developed in the early postoperative period with eventual obliteration of the inferior fornix. The patient declined further management. Minor complications included a central conjunctival dehiscence or necrosis (n = 2) and a pyogenic granuloma that was excised (n = 1). All minor complications healed without sequelae. Overall, 12 % of patients experienced complications (n = 8). Conclusions Based on the low overall complication rate in the present study (12%), the ease of evisceration, the convenience of a single procedure, the rapid resolution of infection, and the successful retention of the Implant in most of our patients, it is plausible to offer evisceration with primary Implant Placement to patients with recalcitrant endophthalmitis or panophthalmitis. This would avoid a secondary surgical intervention in most patients, as opposed to delayed secondary Implantation, in which case 100% of the patients would require, at least theoretically, another intervention.

Alveolar Bone Grafting and Reconstruction Procedures Prior to Implant Placement
Dental clinics of North America, 2012Co-Authors: Harry Dym, David Huang, Avichai SternAbstract:Before Implant Placement, adequate bone must be present; this is a fundamental step in treatment planning for Implants. Understanding the basics of bone grafting and reconstruction techniques is critical for successful Implant Placement. Alveolar bone grafting can be very intimidating when first attempted. With careful instruction, education, and practice, grafting can be accomplished by many practitioners. Different methods incorporate similar surgical principles while leading to the development of more advanced grafting techniques.

Implant Placement post extraction in esthetic single tooth sites when immediate when early when late
Periodontology 2000, 2017Co-Authors: Daniel Buser, Vivianne Chappuis, Urs C Belser, S ChenAbstract:Implant Placement in post-extraction sites of single teeth in the esthetic zone has been a topic of great interest in the field of Implant dentistry since 1990. Triggered by the development of guided bone regeneration, the concept of immediate Implant Placement became quite popular in the 1990s. In the past 12 years, however, the dental community has begun to focus increasingly on the esthetic outcomes of post-extraction Implant Placement and several studies indicated a significant risk for the development of mucosal recessions with immediate Implants. Parallel with this, significant progress has been made in the understanding of tissue biology in terms of hard and soft tissue alterations post extraction, based on preclinical, clinical and radiological studies. This knowledge has helped better to understand the etiology of these esthetic complications with immediate Implant Placement. The present review first analyzes the various phases of the development of therapeutic strategies over the years for post-extraction Implant Placement in single tooth sites in the esthetic zone. It presents the current knowledge concerning the terminology with immediate, early and late Implant Placement, the risk factors for the development of esthetic complications, and the selection criteria for the various treatment options. In the second part, clinical recommendations are given, since a clinician active in this field of Implant therapy can use all treatment options depending on the preoperative analysis including a 3D cone beam computed tomography. The selection criteria for all four treatment options are presented and documented with typical case reports to illustrate the current treatment approaches applied in daily practice.

Timing of Anterior Implant Placement Postextraction: Immediate Versus Early Placement.
Clinical advances in periodontics, 2011Co-Authors: Thomas G. Wilson, Daniel BuserAbstract:Type of Case: Implant Placement in a postextraction site in the esthetic zone is a challenge for clinicians, since esthetic expectations of patients are high and potential esthetic complications can be devastating. The timing of Implant Placement is crucial, since it has an influence on esthetic treatment outcomes and the risk of complications. The topic of this paper is the timing of dental Implant Placement in the esthetic zone in relation to removal of the tooth to be replaced. Two opinions on the topic are presented. The first author (TGW) contends that under certain circumstances, immediate Implant Placement is appropriate in the esthetic zone. The second author (DB) favors early Implant Placement performed after 4 to 8 weeks of soft tissue healing. Both cite literature to substantiate their position and present their current therapeutic approach. Each author has been allowed to review the paper with the opposing view and comment. Clinical Approach #1 (TGW): By definition, an immediate Implant is one that is put into position at the same surgery that the tooth to be replaced is removed. Sites that respond optimally to this approach in the esthetic zone are those with adequate bone for Implant stability and an intact socket. Also important is the complete degranulation of the socket and in infected sites, the use of systemic antibiotics. The best Implant position is normally to the palatal side of the extraction socket. This allows Placement of hard and soft tissue grafts on the facial aspect, which increases the probability of esthetic outcomes. Clinical Approach #2 (DB): Following tooth extraction, early Implant Placement is performed after 4 to 8 weeks of soft tissue healing. This surgical approach allows Implant insertion and simultaneous guided bone regeneration with an intact mucosa, which improves the predictability of contour augmentation. It is done with a resorbable collagen membrane, which is combined with autogenous bone grafts and a low-substitution, hydroxyapatite-based bone filler. In combination with a correct 3-dimensional Implant position, successful contour augmentation provides a low risk for mucosal recession, and a convex contour of the alveolar process. Both are important prerequisites for successful esthetic outcomes.
