Patient recordkeeping is a vast and complex topic. However, by knowing the basics and following the path of least risk, a dentist will find that many practice problems and unwanted complications disappear. The article here explains what the patient record is; why it is maintained and for how long; what it should or should not contain; how to dispose of the record upon retirement, sale of a practice or death, and what to do when a patient wants a copy of the record.
This case report describes the clinical and technical placement procedures for single tooth implant-supported restorations at the time of second-stage surgery. After an implant is placed, its position in relationship to the adjoining teeth can be precisely recorded, using an impression coping and a prefabricated individual resin tray. The tray and the impression coping are joined with self-curing resin and then remounted on the master cast to place an implant analog. The modified master cast is used to fabricate the definitive restoration. Following second-stage surgery, an all-ceramic single crown is placed. The periimplant tissues are molded into position by the definitive restoration, and the healing of the periimplant tissues is controlled entirely by the anatomy of the prefabricated definitive restoration. The learning objective of this article is to familiarize clinicians with placement of implant-supported restorations at the time of second-stage surgery. The method is simple and efficient, and it can also be used with one-phase implant system restorations.

This paper describes a laboratory procedure for use in periodontal and implant prostheses wherein an artificial removable gingiva, which reproduces the patient's gingival architecture, is fabricated on the working cast. This procedure allows the technician to achieve better crown contour and cervical adaptation of the prosthesis and facilitates ceramic procedures.

The advantages of indirect bonding have been recognised for more than twenty years. However the technique has not gained widespread acceptance as an alternative to conventional direct bonding. Reports of difficulty in achieving adequate isolation of posterior teeth and problems with resin flash and low bond strength may explain the reluctance of the profession to make use of the technique. This paper describes an improved indirect technique which uses a heat cured bonding resin in a way that appears to overcome the reported problems.
Titanium is an inexpensive metal that can be used to create custom cast restorations. Although special investment and casting equipment is needed to make titanium castings, the potential benefit of inexpensive, biocompatible, and custom restorations is significant. Porcelain can easily be applied to titanium with excellent bond strength and esthetics. Problems associated with casting roughness and fit can be corrected using electrical discharge machining. A method of diagnosis and treatment planning that evaluates the restorative space prior to implant placement and eliminates the use of machined components is presented.
