RESUMO
An oroantral perforation can occur with the extraction of a premolar or molar in the upper jaw. Small perforations with a deep extraction alveolus can be treated using sutures only; larger perforations are treated surgically, using a buccal sliding or palatal flap. The distinction between small and large perforations can be difficult to make. As a result, oroantral perforations are usually treated by plastic closure. This pilot study presents a new, simple, time-reducing method for the treatment of oroantral perforations using a biodegradable membrane without primary closure of the wound. Six patients with a positive nose-blowing test after extraction were treated according to the new method. In all 6 patients the oroantral perforation was closed after 2 weeks and each showed adequate wound healing after 6 weeks. More research is needed to confirm the results of this preliminary study and the use of this technique on larger perforations.

Prevention of impaction depends in many cases on the knowledge of variations in eruption sequences. However, in case of impaction, spontaneous eruption can be stimulated by exposing the tooth with the modified window-technique. Frequent communications between dentist, orthodontist and oral surgeon are required to determine the right time of intervention.

Delayed eruption of impacted canines in more or less guaranteed by using the modified window technique. A decision for futher treatment can be made afterwards. If orthodontic treatment is required, fixed appliance is recommended for uneventful orthodontic positioning of these teeth.

Attention is paid to the normal and disturbed eruption of the upper cuspid. Genetic factors seem to play the most important role in impaction or delayed eruption. The dentist needs to be aware of the diagnostic and roentgenological features of this phenomenon.

A review of the treatment of the impacted upper cuspid is presented. A description of a modified exposure technique is given. Up to the present day more than 400 impacted cuspids have been treated with this technique.

A modified technique for reconstruction of the atrophic mandible is presented. The caudal part of the mandible is mobilized through a combined intra-extraoral approach or an entirely extraoral approach. The bone graft is then inserted between the osteotomized fragments. The results in terms of bone resorption are comparable with those of the original method, but the risk of a lesion of the mandibular nerve is substantially reduced. Moreover, supplementary vestibuloplasty is only occasionally necessary.
