Titanium Plasma-sprayed (TPS) Screw Implants for the reconstruction of the edentulous mandible

The Titanium Plasma-Sprayed Swiss Screw Implant System is described, with a discussion of preoperative patient evaluation, and implantation and prosthetic techniques. The results in 484 patients in whom these implants were placed in four countries are summarized.

Soft tissue responses to hydroxylapatite particles of different shapes

Fifteen beagle dogs seven to 15 months of age had 0.5 g of hydroxylapatite in the form of sharp-edged particles (HA-1) or rounded particles (HA-2) implanted in buccal soft tissue pouches. Tissue specimens from each site were obtained at two weeks, six weeks, three months, and six months. A mild inflammatory response was seen at the implant sites with both particle shapes; however, inflammation resolved at a faster rate in the sites implanted with round hydroxylapatite particles.

A sixteen-year evaluation of the mandibular staple bone plate

A retrospective study was done of 1,516 patients who had a mandibular staple bone plate operation for jaw reconstruction during the period from 1968 to 1984. The results indicated that 91.75% of the staples were functioning well without major complications, 2.70% were functioning well following repair or replacement, 1.98% were functioning moderately well after unloading (overdenture relief due to mobility), and 3.57% had been removed. The cumulative rate of success was 94.64% for five to six years and 90.89% for ten to 16 years.

A multicenter retrospective review of the mandibular staple bone plate

The mandibular staple bone plate, herein referred to as the staple, has been used as a reconstructive device to improve mandibular function for more than a decade. This report presents the clinical and radiographic findings of a retrospective survey of 160 patients from three separate practices over an eight-year period (1975-1983). The criteria established at the 1978 NIH-Harvard Consensus Development Conference on Dental Implants were used to evaluate results. The study also evaluates experiences with other procedures used in conjunction with the staple.

Oral and maxillofacial reconstruction

Advances in surgical technique and dental implant technology have benefitted both patients and practitioners alike. Earlier diagnosis and treatment, along with increased survival, has made it incumbent on the dental professional to be aware of what can be done for the formerly unrestorable patient. This cooperative team approach works to everyones advantage.

Soft Tissue Response to Different Shaped Hydroxylapatite Particles

Publisher Summary This chapter describes the soft tissue response to different shaped hydroxylapatite particles. Two different types of particulate hydroxylapatite (HA) have been introduced for use in alveolar ridge augmentation and the filling of periodontal lesions. Both are essentially identical in regard to composition and particle size, but are quite different in regard to particle shape. HA-1 is supplied in the form of irregular-shaped sharp-edged, particles and the other, HA-2, is in the form of rounded particles. As bone metabolism and growth is naturally slow and can be affected by subtle differences in the immediate environment, particularly in regard to inflammation, it was of interest to compare the relative inflammatory reactions to these two types of HA particles. The buccal soft tissues of dogs were chosen as the implant site because it was expected that any subtle difference in inflammation would be more readily studied in these tissues. Additionally, the results could have important clinical significance since particulate graft materials may find their way into the soft tissues of the buccal or lingual mucosa. Resolution of inflammation in Beagle dogs proceeds at a much faster rate in soft tissue specimens containing smooth, rounded hydroxylapatite particles, (HA-2) than in specimens containing irregular, sharp edged hydroxylapatite particles (HA-1). This would tend to indicate superior soft, as well as hard tissue compatibility for smooth hydroxylapatite particles when implanted in the oral cavity as a bone substitute.
