Implant procedures 101.

Many practitioners have found implant procedures to be too difficult or too much trouble to perform. Now that restorative components for most implant systems allow for cemented restorations, implant procedures for most clinical situations can be completed in two or three one-hour appointments. This article will review an easy-to-follow restorative philosophy using single- and two-to-three-unit implant restorative procedures that are similar to conventional dental procedures.

Restorative and periodontal considerations of short clinical crowns.

The purpose of this review was to examine the periodontal and restorative factors related to restoring teeth with short clinical crowns. Modes of therapy are usually combined to meet the biologic, restorative, and esthetic requirements imposed by short clinical crowns. The complications presented by teeth with short clinical crowns demand a comprehensive treatment plan and proper sequencing of therapy to ensure a satisfactory result. Visualization of the desired result is a prerequisite of successful therapy. Short clinical crowns present many problems to the restorative dentist. Restorations should have proper form, function, and esthetics while promoting the maintenance of tissue health in the surrounding areas. However, adequate tooth structure for achieving these goals may not always be available. While it is difficult to precisely define minimum crown length, this study offers guidelines for defining a short clinical crown and suggests procedures for achieving a predictable result without compromising the periodontium. The consequences of placing a restoration on a tooth with insufficient crown length are discussed and various treatment methods are reviewed.

Multiple implants for first molar prosthodontics.

Problems that can occur when single implants are utilized to restore first molar teeth include the frequent loosening of screws, as well as screws and/or implant breakage. These may result from torquing and rotational movements of the prosthesis during masticatory and parafunctional mandibular movements. When sufficient bone and mesio-distal restorative space is present, the placement of two implants should be considered.

Guided soft tissue healing in implant dentistry.

Frustrations with creating subgingival implant restorations that are aesthetic and maintainable can be alleviated by using surgical indexing; provisionals as implant copings; or corresponding healing abutments and impression copings. Advantages and disadvantages of each are presented.

Presurgical treatment planning for the anterior single-tooth implant restoration.

The anterior single-tooth implant restoration may be one of the most demanding procedures in dentistry. The edentulous area, implant anatomy, and implant component anatomy are just some of the factors that should be evaluated. Bone dimension, restorative dimension, and their relationship must also be considered. This article will review presurgical treatment planning for the anterior single-tooth implant restoration.

Wide diameter implants: indications, considerations and preliminary results over a two-year period.

Wide diameter implants may be a useful alternative to conventional implant rehabilitation. Despite the fact that most major implant manufacturers are supplying wide diameter implants, very few articles actually address the indications, benefits and results of the use of wide diameter implants. Benefits and indications include increased implant surface area, "back-up" implant for when the initial implant lacks stability, immediate replacement of non-integrated or fractured implants, immediate placement of an implant after tooth extraction, anatomical considerations, increased prosthetic stability and biomechanical factors. Over a two year period, 268 wide diameter implants were placed in 196 patients. Preliminary results are presented in this paper and indicate an overall success rate, up to two years after placement, of approximately 96 per cent. All failures occurred before stage two surgery, due to non-integration of the implant.

Phenytoin hyperplasia occurring in relation to titanium implants: a clinical report.

Dilantin sodium is a commonly used anticonvulsive agent. A well-known side effect of this medication is hyperplasia of gingival tissues. This hyperplasia has also been reported in mucosa beneath complete dentures and has been related to poor oral hygiene. This case report describes hyperplasia of tissues around titanium implants in a patient taking Dilantin sodium to prevent epileptic seizures. The excess tissue was removed and hygiene reinforced. No recurrence of the tissue enlargement is evident after 1 year.
