Plate osteosynthesis of 367 mandibular fractures. The unrestricted indication for the intraoral approach.

Experience in the management of 916 fractures of the mandible stimulated us to develop new methods and surgical techniques for functionally-stable intraoral internal plate osteosynthesis. The development of a fixation bar which is adapted to the alveolar process of the fractured mandible enables a compression of this area prior to the plate osteosynthesis. This procedure facilitates the plate application from the intraoral approach so that in 358 cases all types of fractures of the body, angle and ascending ramus can be reduced using this access, and not only the selected favourable cases. A new plate and screws of our own design have been successfully used in cases with comminuted multifragmentary and defect fractures. The rigid fixation of the head of the screws to the plate produces an optimal functional stability compared with conventional systems. The combination of the advantages of an external fixation device and those of stable internal osteosynthesis produces a long term functional stability even in cases with extensive defects where delayed consolidation is to be expected; tilting and loosening of the screws or resorption of the compact bone underneath the plate do not occur. Thus the extraoral approach and visible skin incisions can be avoided. This procedure is time sparing and less traumatic to the soft tissues compared with the extraoral approach. The extremely low complication rate in 358 fractures managed by plate osteosynthesis using the intraoral approach confirms the efficiency of this method.

[Anterior plating of the cervical spine with the hollow screw-plate system of titanium].

A hollow screw-plate system made of titanium for osteosynthesis of the cervical spine is presented. This system is designed to achieve a stable fixation for fusion of the vertebra. The posterior corticalis of the vertebral body need not and indeed cannot be perforated by the screws. Loosening of the screws is not longer possible because of growth of bone into the lumen of the screw and direct attachment of bone to the surface of the screw.

[Titanium-coated hollow screw and reconstruction plate system for the bridging of jaw defects. II. Possible reconstruction variants with the THRP system].

The advantages and special features of the THRP-system enabled us to develop new operative techniques. The combination of the advantages of external fixation devices and those of the internal osteosynthesis has proved to be decisive in order to obtain good results. The clinical results in 30 patients confirm the recently published findings from animal studies. Histological examination of human specimens comparing 2 types of screws developed by us are discussed.

[The accumulation of osteocementum around a dental implant under physical loading].

Hollow cylinder implants of titanium with a titanium spray surface were implanted in macaca speciosa, as previously described (Schweiz.Mschr.Zahnheilk.86: 713, 1976). This time, however, the implants were submitted to masticatory forces. Histologically it can be shown that the ankylotic contact between implant and bone, which is initially obtained, remains after 6-16 months. In one case the substance encasing the implant at its deepest part was identified as genuine osteocementum.

[Tissue reaction to an implant of a titanium hollow cylinder with a titanium surface spray layer].

A new implant consisting of a hollow cylinder of titanium is described. It is well suited to investigate the tissue reaction to several surface textures in the animal experiment (Macaca speciosa). From a test series, for which the implants were surfaced with powdered titan (titan plasma), one was selected which had been worn for 7 months as a partial support. The solid incorporation observed radiologically presents itself, light microscopically, as an immediate growing in of the bone into the rough implant surface. There is no evidence of the formation of a soft tissue bed. Electron microscope pictures reveal that the bone closely anchored to the titan plasma surface.
