Abstract

Histological examination of 2 porous hydroxyapatite implants removed from a patient showed a pattern of ossification similar to that reported in a previous animal study. New bone was laid down on the surface of the hydroxyapatite but did not progress to occupy all the pores. Although porous hydroxyapatite blocks are biocompatible and well tolerated by the tissues, they are not recommended for augmentation of the resorbed alveolar ridge where the overlying mucosa is thin and atrophic, because of the risk of mucosal dehiscence and implant exposure. They are suitable in situations where they are deeply buried in the tissues and not subjected to direct trauma.

Modified LEAD System distractor to prevent tilting during alveolar distraction in the mandibular symphyseal region.

This report describes a simple modification of the LEAD System distractor that prevents tilting of the distractor rod, and consequent deviation of distraction direction, during alveolar distraction in the mandibular symphysis region.

Influence of the application of platelet-enriched plasma in oral mucosal wound healing.

PURPOSE: The aim of this study was to describe and quantify the therapeutic value of platelet concentrate on the capillary density in oral mucosal wound healing. MATERIAL AND METHODS: The subjects included 10 healthy edentulous patients who underwent bilaterally a sinus floor elevation procedure and a buccal onlay graft with autologous iliac crest bone for maxillary reconstruction. During surgery, platelet-rich plasma (PRP) was prepared from a blood sample taken from the patient. After randomization in a split-mouth design, at one side PRP was administered in the wound and at the contralateral side a placebo. At baseline, microvascular capillary density was scored with the orthogonal polarization spectral (OPS) imaging technique and repeated measurements were performed postoperatively on a daily basis until the tenth day, after which measurements were continued weekly until the fifth postoperative week. RESULTS: Ten patients, five males and five females, were included in the study with a mean age of 54.2+/-9.1 years for females and 57.6+/-6.9 years for males. Donor platelet counts from whole blood had a mean value of 248.5+/-13.5 x 10(9)/l, while the value of platelet counts in the PRP had a mean of 975.9+/-97.9 x 10(9)/l. Wound healing was significantly accelerated in the PRP-treated mucosal wounds during the first 10 postoperative days. After the second week, no obvious differences between the PRP or placebo side could be noted. CONCLUSION: PRP has a strong stimulant effect on capillary regeneration in wound healing. These effects are mainly noticeable during the early stages of wound healing.

Bone formation after sinus augmentation with engineered bone.

OBJECTIVES: The aim of the following investigation was to quantify the resorption rate of tissue-engineered bone grafts in the maxillary sinus using volume measurements. MATERIAL AND METHODS: Sinus floor augmentation using autologous bone grafts from the iliac crest (n=17, group 1) was compared with commercially produced transplants of human cells seeded on polyglycolid-polylactid (PLGA) scaffolds (Oral Bone) (n=14, group 2). RESULTS: The total resorption rate for autologous transplants 3 months post operation was 29%, while the tissue-engineered bone showed a resorption rate of 90%. The autologous bone had a bone density of up to 266-551 Hounsfield units (HU), while sufficient mineralization of tissue-engineered bone was found in only one case (152 HU). CONCLUSION: In this clinical study, the use of autologous cancellous bone grafts in sinus augmentation was more reliable than scaffolds containing cultured osteoblasts. Further tissue-engineered bone transplants should be examined to draw general conclusions about the use of tissue-engineered grafts compared with autologous bone grafts for maxillary sinus augmentation.
