Indications for surgical removal of 2,630 impacted mandibular third molars were studied. The investigation comprises all operations during a period of 12 months and was carried out at 4 departments of oral surgery within the Stockholm area. The average age of the patients was 27 years. Pathological changes were seen in about 60% with pericoronitis as the(More)
This study investigated the occurrence of corrosion associated with the use of metallic implants to stabilize jaw fractures. Three different types of plates, Co-Cr and Ni-Cr alloys and Titanium, were connected in vivo to the mandibular bone surface of monkeys (Cercopithecus aethiops). The animals were killed after 3 and 6 months. The mucous membrane and(More)
Pathological changes related to impacted 3rd molars (ITM) were studied in a radiographic investigation of 2128 randomly selected patients. In radiographs from 644 patients, 1211 ITM were noted. Pathological changes were observed in 25 of 477 (5.2%) maxillary ITM and in 59 of 734 (8%) mandibular ITM. A pathologically widened pericoronal space (indicating a(More)
Ten patients undergoing treatment with bridges supported by osseo-integrated oral titanium implants were studied regarding the oral microflora. Saliva samples for microbiological studies were collected before the abutment operation, 1 week after the operation, after the bridges were inserted and again 52 weeks after the abutment operation. The implants did(More)
In a series of monkeys, titanium implants (Xenodent) were installed in the sockets of mandibular incisors. The animals were sacrificed 7 and 12 weeks after the implantations. The healing was studied by histological and microradiographical techniques. A gradual osseointegration free from adverse interference could be noticed.
A random material of 112 patients, was investigated after surgical removal of impacted lower third molars. 2 experimental groups and 1 control group were studied. Prophylactic medication with penicillin V combined with preoperative rinsing using 0.2% chlorhexidine gluconate (Hibitane) was found to reduce postoperative symptoms, when compared with(More)
The material comprised 222 assault victims whose injuries required attention at the Departments of Oral Surgery and Ear, Nose, and Throat diseases, the Central Hospital in Falun or corresponding departments at the Karolinska Institutet, Stockholm or the University Hospital in Huddinge. Information was obtained from patient records. One hundred and(More)
Tooth loss can be a problem when orthodontic appliances have to be stabilized for treatment. It has been shown that endosseous titanium implants are well integrated during treatment of edentulous patients with intra-osseous anchored bridges. In the present investigation titanium implants were inserted immediately after tooth extraction. After(More)
