The effect of occlusion on periodontal disease has long been controversial. There are a few studies showing the benefit of occlusal therapy in the treatment of periodontal disease. This paper discusses these studies in an effort to give guidelines for treatment of occlusal trauma and its relationship to periodontal therapy.
A total of 288 patients (100 females and 188 males) aged 25 to 60 with prognathic and progenic occlusion were examined and treated. Dentition deformations were revealed in 182 (63.1%) patients. Clinical and x-ray signs of traumatic occlusion were observed in 219 (76.04%) cases. Abnormal mobility of teeth was detected in 181 (79%) subjects with prognathic occlusion, dentogingival and osseous pouches in 164 (71.6%) subjects. Reduced height of occlusion was found in 68 (25.3%), dysfunction of the temporomandibular joint in 19 (8.2%) cases. Traumatic occlusion was observed in 38 of the 59 patients with progenic occlusion. In sagittal abnormalities of occlusion, traumatic occlusion was associated with dysfunctions of the masticatory muscles and of local circulation in the periodontium, which were recorded by electromyography and rheoparodontography. The treatment was carried out by therapists, surgeons, and orthodontists. Orthodontic treatment consisted in levelling of the occlusion surface of dentitions, orthodontic preparation of the maxillodental system, fitting with splints and prostheses. Remote results in periods from 1 to 3 years were good in 94.8% of patients.
The experience of use Michigan splint for temporary splinting of the maxillary tooth at realization of flap surgery at 23 patients. Stages of clinical and laboratory procedures making the splint are described and analysed. Is appeared, that the reduction of mobility of teeth in the period following surgical intervention occurs on the average within 0.5-1 month faster, than with the patients after similar interventions, but without splinting. At the same time it is proved obvious, that the usage Michigan splint promotes normalization of functioning of muscles activity masticatory system and TMJ and helps in revealing of occlusal interferences.

The aim of this study was to demonstrate the suitability of the FAMI screw (fixation and adaptation in mandibular injuries) for maxillomandibular fixation in the maxillofacial area in orthognathic and trauma surgery. This FAMI screw was used in 28 patients for maxillomandibular fixation with wiring or elastics. The screw is inserted into the labial or buccal surfaces of the alveolar process without predrilling. Adequate intermaxillary fixation with balanced occlusion was created intraoperatively in all patients. In comparison with conventional splinting methods, this technique was far less time-consuming. The use of the FAMI screw has the advantage of being quick and simple, particularly if only a brief period of maxillomandibular immobilization is planned. Furthermore, the risk to the surgeon of sustaining a puncture injury from wire ligatures is distinctly reduced. Screws can be removed without local anesthesia. The above-mentioned method is minimally traumatic, effective, timesaving, and hence inexpensive. It can be used for maxillomandibular immobilization in dentate as well as in edentulous patients.
The bite registration is one of the most important steps in any restorative or occlusal case. Bite registrations are used for study models, provisional restorations, splint construction, and restorative dentistry. The author has tried many methods and materials and has found that the above technique works extremely well, can be repeated easily, and simplifies the mounting of the opposing cast. Other materials (such as polyvinylsiloxane) sometimes are too spongy and do not offer a solid seat for the lower model. The most important thing to remember when using any method is to pay attention to detail at every step. Step one must be completed to the highest level prior to continuing to step two, and so forth. Excellence in restorative dentistry depends on patience and exacting technique.
