ABSTRACT: Abstract Objective: To demonstrate the efficiency of Er:YAG laser for removal of laminate veneers in case of fracture. Primary modes of failure of porcelain laminate veneers were noted to be fracture, microleakage, or debonding. Background data: One of the predisposing factors for the occurrence of fractures is heavy functional or parafunctional loading. Methods: Removal of fractured laminate veneers with Er:YAG laser is proposed as a reliable method. Two cases are presented in which fractured laminate veneers were removed with Er:YAG laser. The parameters used for removal were set at 20 Hz/320 mJ, with water irrigation for 9 sec and the chisel-type laser tip was selected (1.2×0.4 mm, rectangular shape). The pulse width was 200 ms. Results: The laminates were removed without any damage to the underlying tissue. The new restorations were reconstructed and both patients were taken under recall program at 6-month intervals. Conclusions: The removal of fractured laminate veneers with Er:YAG laser could be a suitable alternative in routine clinical use.

ABSTRACT: The looseand unstable lower complete denture is a common problem faced by denture patients. One method used to solve this problem is the neutral zone technique. The neutral zone is the area where the displacing forces of the lips, cheeks and tongue are in balance. In the clinical report presented here, a severely resorbed lower alveolar ridge was treated by determining the neutral zone with tissue conditioner material (Visco-gel, Dentsply Ltd., Weybridge, U.K.). The neutral zone approach with Visco-gel is a more practical and economically feasible treatment for patients having atrophic mandibular ridge.

ABSTRACT: There are multiple factors in cases of mandibular hypomobility. One of these factors is elongated coronoid process. Two cases are presented to illustrate elongated coronoid process leading to mandibular hypomobility to help prevent misdiagnosis by clinicians. Coronoid process elongation is a rare condition. Both cases reported here had pulpitis on the teeth, however endodontic treatment could not be performed due to the restricted mouth opening in both cases. There were clinical findings of restricted range of motion, especially during protrusive movements. The restrictive movements did not cause pain for either patient, and the patients were not aware of their restricted mouth opening. Panoromic radiographs were taken and evaluated. The radiographs showed elongated coronoid process bilaterally. Three-dimensional computerized tomography was taken in one case only, due to the patient's financial restrictions. In cases of restricted mandibular opening, elongated coronoid process must be considered when diagnosing the cause.

ABSTRACT: This study evaluated and classified the radiographic appearance of the styloid process (SP) patterns of calcification according to subject gender. The relationship between SP length and the limits of mandibular protrusion was studied.
The panoramic radiographs of 55 young adults were analyzed. Elongated SPs were classified with the radiographic appearance based on length, morphology, and calcification pattern. The data were analyzed by using chi-squared and 1-way ANOVA with significance set at P < .05.
"Elongated" (Type I) SP with "calcified outline" was the most frequent SP type and calcification pattern. No correlation was found between SP type and calcification pattern and subject gender. No differences were proven based on laterality of the SP. A relationship between mandibular protrusive movement and SP calcified length was not proven.
Elongation of calcification of SP in young adults is common with no correlation to gender, laterality, or mandibular protrusive limitation. "Type I" with "calcified outline" of the SP was observed most frequently in the population studied.

ABSTRACT: In 1942, Stafne was the first to report radiographic findings of "static bone cavities" situated near the angle of the mandible. The typical radiographic appearance of Stafne's mandibular defect is a radiolucency below the inferior alveolar canal, between the mandibular premolars and the angle of the mandible. Stafne's mandibular defect ranges from 10 mm to 30 mm in diameter. The size has been shown to be remarkably constant in diagnosed lesions followed over time. In the majority of cases, the lesion is symptomless. Routine surgical exploration is not indicated. It is suggested that the lesion is a radiographic rather than a pathological entity; therefore, consideration was given to making use of these anatomical retentive areas in a prosthetic manner. In this article, a literature review of Stafne's mandibular defect is presented and attempts to improve the retention and stability of the lower complete dentures by using this anatomical entity are described.
