Implant placement and provisionalization in extraction, edentulous, and sinus grafted sites: a clinical report on 1,500 sites.

The incorporation of restorative procedures at implant placement and the creation of natural emergence profiles and lifelike ceramic restorations have become the focus of implantology. Recent publications have provided guidelines for success with the immediate restoration procedure, and have presented basic surgical protocols for the implant team. Enhancement of the healing phase through the local delivery of growth factors to the surgical site, as well as through advancements in bone grafting materials, has allowed implant surgeons to accomplish multiple surgical procedures during the initial surgical visit. In addition, advancements in surgical stent designs have allowed the restorative dentist to adequately communicate to the surgeon, during surgery, the parameters required in the final restoration to replace the natural tooth system with form, function, and esthetics. This article presents the results of more than 1,500 immediate restored implants placed in edentulous sites, fresh extraction sockets, and sinus grafted sites. Also highlighted are guidelines for surgical success, as well as a description of a surgical stent design that communicates requirements for restorative success to the surgeon, while also serving as an esthetic provisional restoration.

Review of factors contributing to dry socket through enhanced fibrinolysis.

Use of oral contraceptives and trauma during extraction are substantiated factors that contribute to dry socket. They appear to act by enhancing fibrinolytic activity in the alveolar bone followed by lysis of the clot. The influence of bacteria and antibiotics on the development and prevention of dry socket remains unclear. No convincing evidence can be found that factors such as age, sex, or nutritional status affect the incidence of dry socket.

Alveolar wound healing after x-irradiation: a histologic, radiographic, and histometric study.

Healing of extraction wounds in rats following cephalic irradiation was studied by histologic, radiographic, and histometric methods 14 days after tooth extraction. Irradiation was given at 0, 3, and 7 days after surgery in doses of either 15, 20, or 30 Gy. No significant differences were seen with the different doses given seven days post-extraction. However, socket healing was delayed when irradiation was given immediately and three days after extraction. On the basis of these observations, it is recommended that radiation not begin until at least one week after the extraction of teeth.

Jawbone cavities and trigeminal and atypical facial neuralgias.

The possible role of dental and oral disease in the etiology of idiopathic trigeminal and atypical facial neuralgias has been examined. Among thirty-eight patients with idiopathic trigeminal neuralgia and twenty-three patients with atypical facial neuralgia, there was in nearly all instances a close relationship between pain experienced and the existence of cavities in alveolar bone and jawbone of the patients. The cavities were at the sites of previous tooth extractions and, although at times more than 1 cm. in a given diameter, were usually not detectable by x-rays. A new method for their detection and localization was developed empirically, based on the observation that peripheral infiltration of local anesthetic into or very close to the bone cavity rapidly abolished trigger and pain perception by patients during persistence of the anesthetic action. Histopathologic examination of bone removed from cavities by curettage revealed, in both idiopathic trigeminal and atypical facial neuralgias, a similar pattern characterized by a highly vascular abnormal healing response of bone. Some lesions presented a mild chronic inflammatory (lymphocytic) infiltration. Preliminary microbiologic studies of material from the walls of the cavities showed the existence within them of a complex, mixed polymicrobial aerobic and anaerobic flora. Treatment consisted of vigorous curettage of the bone cavities, repeated if necessary, plus administration of antibiotics to induce healing and filling-in of the cavities by new bone. Responses of patients to the above treatment consisted of marked to complete pain remissions, the longest of which has been for 9 years. Complete healing leads to complete and persistent pain remissions. It was concluded that in both idiopathic trigeminal and atypical facial neuralgias, dental and oral pathoses may be major etiologic factors.

Mandibular third molar removal: risk indicators for extended operation time, postoperative pain, and complications.

OBJECTIVES: The aim of this study was to identify risk indicators for extended operation time and postoperative complications after removal of mandibular third molars. STUDY DESIGN: There were 388 molars included in the study. The teeth were removed using the buccal approach under local anesthesia. Four hours postoperatively the patient recorded his or her pain perception on a visual analogue scale (VAS). After surgery a surgeon recorded parameters regarding the tooth and if the mandibular nerve had been visible during the operation. One week postoperatively the postoperative pain and complications were recorded. Logistic regression models were made to identify risk indicators for extended operation time, postoperative pain, and complications. RESULTS: Females were at higher risk for postoperative pain and dry socket than males. Older patients were at higher risk for extended operation time than younger patients. Radiographically fully impacted molars increased the risk of postoperative general infection. If the nerve was visible during surgery there was a higher risk of a high VAS score, postoperative pain, and general infection than if the nerve had not been visible. CONCLUSION: Several indicators were found to increase the risk of postoperative complications, but a visible alveolar inferior nerve during the operation was repeatedly found to be the highest single risk indicator.

Effect of azidocillin, erythromycin, clindamycin and doxycycline on postoperative complications after surgical removal of impacted mandibular third molars.

Treatment of osteitis after surgical removal of the third molar of the mandible is still a clinical problem. A total of 140 patients undergoing operations for removal of an impacted third molar of the mandible, were included in a double-blind study. Placebo or antibiotics - azidocillin, erythromycin, clindamycin and doxycycline - were given to the patients preoperatively and for the following 7 days. The concentrations in serum, alveolar serum and mandibular bone were measured and the postoperative courses - pain, trismus, swelling and wound-healing - were recorded. No correlation was obtained between the antibiotic concentration and the postoperative complaints, except in the azidocillin group on day 2, in which fewer complaints were noticed in patients with high concentrations of the drug at the time of operations. The 80 patients in the antibiotic groups responded significantly better with respect to wound-healing than the 60 patients in the placebo groups. Only 15 operations lasted more than 15 min and the three of them which subsequently resulted in alveolitis were in the placebo groups. Antibiotics significantly reduced pain on day 7 postoperatively. In general, no statistically significant differences in trismus and swelling could be demonstrated between the patient groups. However, there was a significant difference between the placebo and doxycycline groups with respect to swelling (day 2 postoperative, P < 0.01; day 5 postoperative, P < 0.05). Thus systemically administered antibiotics offered only slight advantages in routine operations of impacted third mandibular molars, but could decrease the rate of infections after traumatic operations.

Effects of gender-related factors on the incidence of localized alveolar osteitis.

Numerous literature references have suggested increased risk for localized alveolar osteitis associated with female gender, use of oral contraceptives, and point in menstrual/contraceptive cycle. However, the available information has not been systematically considered with the intent to accurately estimate the magnitude of these effects. The present review suggests that under certain conditions, some of which may be avoidable, females may have at least a two to threefold increase in osteitis risk compared with males. It appears that this greater risk may be reduced by considering hormonal cycles when scheduling elective exodontia.

Impacted mandibular third molars: depth of impaction and surgical methods of extraction among Nigerians.

This study was conducted in three centres. 717 impacted mandibular third molars were extracted from 517 patients. 69.1% of the extractions were in patients aged 25 years and below. A total of 96.1% extractions were done under local anaesthesia while 3.9% were under general anaesthesia. The lingual bone split technique was used in 2.5% extractions while the bur was used in 97.5% extraction. The patient's preference, the number of teeth to be extracted, and the depth of impaction were the main predicators in the choice of anaesthesia. Majority of third molars with a depth of 5 mm or more were extracted under local anaesthesia. Paraesthesia of the inferior dental nerve and alveolar osteitis were more frequent when extractions were done using the bur technique under local anaesthesia, while paraesthesia of the lingual nerve was more when extractions were performed using the lingual bone split technique under general anaesthesia.
