Mandible fragment fixation during reconstruction: the splint-and-plate technique.

One of the most popular methods of mandible fragment fixation is the precontoured reconstruction plate technique. Unfortunately, this method is not a reliable option when tumor distorts the mandibular contour or extends through the buccal cortex of the mandible. An alternative to the precontoured reconstruction plate is the splint-and-plate technique of mandible fragment fixation. An application of this appliance and method in 10 patients revealed the technique's advantages. The splint can be applied quickly and does not obstruct the ablative or reconstructive procedure. Further, the splint accurately keys the dentition and reliably maintains temporomandibular joint relationships. Finally, this technique provides a reference point to the exact position of the symphysis and angle when these landmarks have been resected.

Probing site configuration in patients with untreated periodontitis. A study of horizontal positional error.

This study examined the morphology of 487 probing sites in patients with untreated periodontitis, using a constant force probe (0.25 N, 0.5 mm) and flexible stent with guide grooves, at 3 adjacent points per site, 6 sites per tooth. Sites were classified into 9 configuration types according to the relationship of the 3 adjacent points. Duplicate measurements were made and sites were analysed with special reference to whether a slight horizontal movement was likely at the second examination. 60% of individual point probing measurements were exactly reproduced, but only 23% of site configurations. 65% of configuration change was accountable on the basis of slight horizontal shift of the probe. Only 13% of configurations required the postulate of other forms of probing error. These results suggest that probing reproducibility is not always an indication of site reproducibility, and that the variation of probe position in the transverse plane is an important source of probing error, even when a stent is used.

Reverse Maryland bridges: clinical applications.

The "Maryland Bridge" or the etched metal-composite bonded retainer has experienced a variety of clinical applications since its inception as the etched enamel plastic-bonded Rochette periodontal splint. Through the evolutionary stages of different metals and framework preparation for composite bonding by electrolytic, chemical, and air-abrasive procedures and the improvements in bonding composites, the bridge has been in clinical use for approximately 9 to 10 years. Certain clinical and radiographic criteria must be satisfied prior to using the conventional Maryland bridge, but with the unique application of the basic bridge design modified and placed from the labial or buccal position some previously contraindicated uses of the bridge can be reversed by using a unique, if not provocative, application of the bridge design principles. This article presents two clinical case reports utilizing the Maryland bridge applied from the labial and buccal aspect. Both fixed partial dentures presented have been in place clinically for over 18 months, whereas others of this type have been successfully in place for over 6 years.

Non-surgical approach to advanced chronic periodontitis: a 17.5-year case report.

This 17.5-year longitudinal case report details the treatment of advanced chronic periodontitis in a female patient commencing at 34 years of age. The woman was provided with periodontal care comprising of temporary fixation, scaling and root planing, intra-pocket irrigation using a root canal syringe and regular supervised maintenance. The patient presented with a 10-year history of bleeding gums. Therapy conducted in general practice had included simple curettage and irrigation. However, these treatments proved unsuccessful and the patient often changed dentists seeking better treatment. She presented to the University Dental Hospital, for diagnosis and treatment of her periodontal conditions after her mandibular lateral incisor had exfoliated. On presentation a purulent exudate could be expressed from all of the pockets. All anterior teeth, excluding the maxillary canines, demonstrated +2 to +3 mobility. The patient did not want any surgical treatment or her teeth extracted. It was decided to treat the patient conservatively without surgery. By postponing extraction, the authors were in a better position to determine the prognosis of the remaining teeth after the infection was under control. Although six teeth were extracted during the 17.5 years, this case report suggests that a non-surgical approach is a viable option while maintaining regular visits for periodontal care.

Gold as an implant in medicine and dentistry.

The purpose of this collective review is to study the history, physical and chemical properties, application, and clinical consequences of gold implants in the dental and medical fields. Gold implants are used in various medical procedures, including reconstructive surgery of the middle ear, upper lid closure in facial nerve paresis-induced lagophthalmos, drug delivery microchips, antitumor treatment, treatment of rheumatoid arthritis, use on the surface of voice prostheses, and endovascular stents, with sound clinical results. However, in order to achieve better therapeutic benefits, clinical reports have documented that the surface of gold implants have been modified or encased in biocompatible alloplastic materials, or they have been replaced by cheaper and more biocompatible materials. Gold is also applied to a long list of dental prostheses, including inlays, onlays, crowns, bridges, periodontal splints, and post and cores. It has sufficient strength and corrosion resistance, and it is relatively biocompatible. In addition, gold dental prostheses have a long life cycle. However, esthetic concerns and cost make it a less desirable prosthesis today than in the past.

[Results of conservative and surgical treatment of jaw fractures].

In the majority of the patients with fractures of the jaws treated in the period covered by this study, conservative therapy has shown satisfying results. In intraoral splinting, periodontal lesions could largely be avoided by adequate oral hygiene. Surgery must still be applied in those cases where conservative methods failed to be successful.

The use of orthodontic intrusive movement to reduce infrabony pockets in adult periodontal patients: a case report.

Clinicians often encounter osseous defects that are best treated by conventional surgical techniques, including bone grafting and guided tissue regeneration, with a goal of establishing a new connective tissue attachment. On occasion, the recognition of an infrabony defect proximal to a tooth with a large diastema may present an opportunity to consider resolution by orthodontic tooth movement. Ideally, the tooth could be moved in the proximal direction until there was no further radiographic or clinical evidence of the predisposing defect. The authors decided to treat an advanced case of adult periodontitis, with extrusion and migration of a maxillary central incisor, using a multidisciplinary approach. Radiologically, a large infrabony defect was present on the mesial aspect of the incisor, with an initial probing depth of 9 mm. After the surgical periodontal therapy, the orthodontic movement started and the incisor was repositioned using an intrusive mechanism, also leading to the closure of the diastema. At the end of the treatment, there was a significant clinical decrease in the probing depth values, and radiographs showed a remarkable reduction of the infrabony defect volume.

Considerations in treatment planning of the periodontal patient.

Through the use of periodontal, orthodontic, and restorative procedures, this patient was restored to function with a stable dentition and minimal pocket depths. The patient was followed for 10 years. All areas exhibited a healthy periodontium with stability of all areas of the dentition.

[Analysis of stresses in modified resin-bonded cast fixed partial dentures].

In 1973, ROCHETTE introduced a periodontal splinting method that involved bonding of cast perforated retainers to the acid etched lingual surfaces of anterior teeth, using a resin. Nowadays, there have been a number of reports on the clinical performance of the adhesive bridges. The objective of this investigation was to photoelastically evaluate the forces exerted on the supporting structures of abutment teeth by modified resin-bonded cast fixed partial dentures. Four modified designs were tested and a traditional fixed bridge used as a control design. This study indicated that the resin bonded cast fixed partial denture with the lingual chamfer margin and mesial rest was the design to be chosen.
