- The magnitude of projection errors, calculated theoretically on length measurements in cephalometry was studied. Rotation of the object by up to 5° from the proper position, resulted in errors in length measurements that were usually less than one percent. Rotations of more than 5° may increase the error but imply misalignments of the head that should be evident when positioning the patient. The advantage of extremely long focus film distances seems doubtful.

Effect of preoperative paracetamol on pain after oral surgery.

- A double-blind, randomized cross-over trial was carried out in 50 patients undergoing surgical removal of bilaterally impacted lower wisdom teeth. Surgery in each patient was performed twice and paracetamol 1000 mg was administered once preoperatively and once postoperatively. The time interval to additional analgesic intake and the pain intensity up to and at that time were assessed. There was no difference between the 2 treatments. It was concluded that preoperative paracetamol does not offer any clinical advantage in patients who undergo surgical removal of impacted lower wisdom teeth.

Combined use of bone grafts and Brånemark fixtures in the treatment of severely resorbed maxillae.

Tidskriftsartikel (refereegranskat)abstract
- Bone grafts from the hip in combination with Brånemark self-tapping fixtures have been used to rehabilitate patients with extremely resorbed maxillae. Experiences and results from the first ten consecutive cases have been analyzed to form the basis for further use of the method. Eight of 57 fixtures placed have been lost to date. Surgical complications, including exposure of the bone transplant, have occurred in three patients. The method should be used with caution, and cases should be meticulously chosen to exclude those who do not have proper motivation to endure the long-lasting and demanding surgical and prosthetic procedures required. The combined use of implants and transplants should not be used routinely until a long-term evaluation of the method and results has been made.

Extraoral or intraoral approach in the oblique sliding osteotomy of the mandibular rami? Clinical experience and results.
- 1987
-
Ingår i: Journal of Cranio-Maxillofacial Surgery. - 1010-5182 .- 1878-4119. ; 15:5, s. 233-237
-
Tidskriftsartikel (refereegranskat)abstract
- The clinical results of oblique sliding (subcondylar) osteotomy of the mandibular rami performed by the extraoral or intraoral approach were compared. The patient material comprised 40 patients with mandibular prognathism. Twenty patients were operated upon using the extraoral approach and 20 patients were operated on using the intraoral approach. All patients had intermaxillary fixation for 7 weeks. The patients in both groups were followed up for 18 months. The experience of the operations was that the intraoral approach gave a shorter operation time than the extraoral approach. The extraoral approach, however, gave better visibility in the operation field and greater possibilities of manipulating the proximal fragment into an optimal position. In the follow-up evaluation, there were no significant differences between the two surgical techniques with regard to dental relapse, post-operative occlusion and mandibular function.

Intraoral or extraoral approach in oblique sliding osteotomy of the mandibular ramus. A cephalometric study.

Tidskriftsartikel (refereegranskat)abstract
- Positional changes of the mandible after oblique sliding osteotomy of the mandibular rami were investigated by means of cephalometric analysis. The patient material comprised 40 patients. Twenty patients were operated upon using an extraoral approach and 20 were operated on using an intraoral approach. The patients were followed up with lateral cephalograms for 18 months after operation. In both groups, a posterior rotation of the mandible took place during the fixation period. This rotation gave a further retro-displacement of gnathion and a shortening of posterior facial height. The incidence of patients with considerable posterior rotation of the mandible was higher in the intraoral than in the extraoral group. The difference between the means of the changes in the mandibular plane angle (dEO = 4.9 degrees, dIO = 6.3 degrees) of the groups was, however, not statistically significant. Nor was there any significant difference in relapse between the two groups after release of the fixation.
