ABSTRACT
Single tooth replacement with a dental implant is an increasingly popular solution in patients with loss of an upper anterior tooth. There is a risk, however, of placing the implant prematurely in youths. In a case series the effects of residual maxillary growth on the results of implant treatment in the anterior maxillary region were measured. The results confirm findings from other studies on this subject and indicate that cessation and degree of vertical growth are unpredictable. This may result in infraposition of the implant and lead to periodontal bone loss around the implant region and its neighbouring teeth. Clinicians should be aware of this and inform their patients that these changes may eventually compromise the aesthetic result of the treatment.

Between 1982 and January 1991, 2454 ITI Bonefit implants were placed in 841 patients. The clinical data were gathered from the departments of oral and maxillo-facial surgery at hospitals in Breda, Leiderdorp and Zwolle, the Netherlands. The follow-up ranges from one year to 9.5 years. A total of 48 implants were lost (2%).

The single hollow titanium cylinder implant type F is here described. From october 1983 till october 1988, 187 implants were placed in 56 patients. It is possible to use this implant as a replacement for a single tooth or as abutment for a bridge. In case of extreme bone loss of the edentulous jaw, this implant is suitable to create retention and stabilisation for a denture. Up till now 180 implants are in function (96%); 7 implants were lost because of early failures.

In cases of extreme bone loss of the edentulous jaw, nowadays, implants are suitable to create retention and stabilisation for the dentures, next to the wellknown preprosthetic surgical techniques. It is also possible to use this implant as replacement of a single tooth or as abutment for a bridge. The single hollow titanium cylinder implant type F is described. Also the surgical technique for application of this implant is explained. In the period October 1983 till December 1987, 126 implants (39 patients) were placed; eight of them are removed (6%).

In 45 patients a preformed polymethylmethacrylate (PMMA) cranioplasty prosthesis was inserted. The cranial defects mainly were caused by trauma, removal of tumour and secondary infection of bone after intracranial operation. Several broken peroperatively cold-cured acrylic plates were replaced by preoperatively molded PMMA plates. The longest follow-up was seven years and the shortest four months; the average was 39 months. The size of the defect ranged from 6 cm2 to 175 cm2. The average age at operation was 33 years; the youngest patient was one year, the oldest 74 years. There were no acute postoperative complications. Two plates had to be removed nearly one year after insertion. Both patients had a long history of chronic bone infection before the PMMA cranioplasty was performed. The technical details will be described; the advantages of the method will be discussed.

A method of stable fragment fixation in maxillary and mandibular orthognathic surgery is described. In 30 cases, the follow-up was long enough (one to five years) to promote review of the results. As expected, stability and wound healing were excellent. The method is comfortable for the patient, prevents excessive weight loss, and reduces postoperative morbidity and the length of stay in hospital. The incidence of permanent damage to the mandibular alveolar nerve is the same as with conventional fixation methods. Special attention was given to the possible occurrence of TMJ problems that might result from the condylar rotations. Neither clinical or radiographic evidence of TMJ damage could be established. The method of stable fragment fixation can be especially advocated in bimaxillary and edentulous cases and cases prone to osseous relapse.

A case is presented of a large, multiloculated primordial cyst in the lower jaw. In treatment planning of the lesion, a hemimandibulectomy had been seriously considered, but seemed to be too agressive a therapy for a non-malignant lesion. However, the recurrence rate of multiloculated cysts made a meticulous enucleation necessary. By employing a sagittal splitting of the right half of the mandible a good surgical access was provided and the cysts could be removed very thoroughly. Recurrence was not observed during a 3 years follow up period.

Quantitative data on pain, trismus, and swelling after removal of a mandibular third molar are presented. The population of 932 patients included both extractions and surgical removals. Frequency distributions of trismus and pain are given. For all complaints the behavior of the average value as a function of time is presented and these functions are compared with each other. For all values measured on the 3rd and 4th posttreatment days, correlation and regression coefficients for the effects were calculated. It is concluded that there exists a rather strong, but time-dependent, interrelationship between the complaints.

Quantitative data on postoperative complaints and complications after removal of the mandibular third molar, especially in relation to the different methods of treatment, are scarce. Mostly an objective approach is lacking. The present study attempts to provide such data and their clinical consequences. Within 1 year, 932 mandibular third molars were removed; 430 extractions served as a control group for 502 surgical removals. The procedure was fully standardized and all measurements objectively obtained. A computer was used for statistical evaluation. It appeared from this study that the possibility of postoperative complaints and complications will be smaller if the wound is not packed, if tight suturing is not done and if reflection of the mucoperiosteum is avoided. If reflection is inevitable the oblique vertical relaxing incision is preferred. Prophylactic administration of antibiotics is rejected.

Lower third molars are often removed, because of complaints such as pain and trismus. A survey of 932 lower third molars reveals that abnormal position, caries or inflammation the direct reason are for removal in 9 out of 10 cases. So prophylactic removal is necessary. The best time is between 15 and 25 years of age.

No objective method for measuring postoperative swelling both simply and reliably is known from the literature. The method described in this article measures the degree of swelling indirectly by comparing tracings of pre- and postoperative photographs printed full-size. The photographs taken are standardized and full-face. The head is reproducibly fixed by means of a bite impression and two rings. One ring is mounted on a table on which the camera also is fixed. At the other, mobile, ring the bit impression is fixed. Three-point contact in the correct position between the two rings is signalled electrically, so that the head is in the correct position and the photograph can be taken. The advantage of this method over a rigis connection between bite fork and fixation stand on the table is that distortion or even bending of the fork and connecting bar is not possible. Experience with this method shows that in 95% of the patients photographed the picture was exactly reproducible. Measuring non-operated test persons revealed the reproducibility of the cheek contour to be better than 0.2 mm. The error made when tracing the photographs is of about the same magnitude.
