Purpose: Distraction osteogenesis is considered to take favorable effect on the TMJ and be beneficial to prevent the relapse after the mandibular advancement of Class II malocclusion patient. This is the report with literature review on the mandibular advancement in the patients showing preoperative condylar resorption and who need larger amount of advancement. Patients and method: Distraction osteogenesis using intraoral device was performed for three mandibular hypoplasia patients (one male and two females). All patients were adult over 18 years old. The patients showed condylar bony resorption preoperatively. The distraction was performed intraorally with modified SSRO. After 7 days of latency period, activation was performed at the rate of 1.0 mm/day with twice turn. The devices were removed after 4-8 month consolidation period. Results: Total advancement of mandible was average 13 mm. One patient showed openbite immediately after removal of distraction device. It took long time to guide the openbite with elastics. The comparison between cephalometries immediately after device removal and postoperative six month revealed average 3.4 mm relapse. This means that mandibular advancement with distraction osteogenesis needs overcorrection and elastic rehabilitation even after enough consolidation periods. Conclusion: Larger amount of mandibular advancement could be achieved with distraction osteogenesis in severe mandibular hypoplasia with condylar resorption. However, some relapse was found during the follow-up period and the over correction is considered to be needed. The effect of distraction osteogenesis seems to be investigated with long-term follow-up.

Objectives: Distraction osteogenesis has recently evolved a challenging technique to overcome the limitations of conventional augmentation procedures. The aim of this report was to evaluate the clinical result of alveolar distraction osteogenesis for implant installation. Methods: Twenty five patients with alveolar ridge deficiencies were treated with vertical alveolar distraction osteogenesis by intraoral device (total 27 devices: 25 extraosseous and 2 intraosseous devices). After the latency periods of 5-7 days, activation of the device was started. The distraction rhythm and rate was 0.75-1.0 mm a day with 2 or 3 times a day. After 3-4 months, dental implants were placed with removing the distractor simultaneously. Results: On average, a vertical gain of $9.8{\pm}3.4\;mm$ was obtained by distraction osteogenesis. Total 84 implants were installed. Average follow up period was $13.5{\pm}7.5$ months. No implant was removed during the follow up period. Three patients showed infection during the distraction osteogenesis. Three devices were broken and 2 devices among them were replaced with new one. Conclusion: Relatively larger amount of alveolar bone augmentation could be obtained with distraction osteogenesis. For the ideal anatomically and functionally ideal regeneration of alveolar bone to install dental implant, the complication of distraction should be controlled.

The inferior alveolar nerve (IAN) block is the most frequently used mandibular injection technique for achieving local anesthesia for restorative and surgical procedures. However, The IAN block does not always result in successful anesthesia, especially pulpal anesthesia. Lidocaine is used as a "standard" local anesthetic for the inferior alveolar nerve. Articaine recently joined Korean market as a form of dental cartridge. It has an advantage of superior diffusion through bony tissue. A variety of trial was performed to improve the success rate of inferior alveolar nerve block. In this review, the recent update related with inferior alveolar nerve block anesthesia will be discussed on the anatomical consideration, anesthetic agent, technique, and complications.

Masticatory function is related to the complex function of oral cavity. Mastication, saliva, and taste are functional part of the preparation of food. Mastication is a sensory-motor activity aimed at the preparation of food for swallowing. It is a complex process involving activities of the facial, the elevator and suprahyoidal muscles, and the tongue. These activities result in patterns of rhythmic mandibular movements, food manipulation and the crushing of food between the teeth. Saliva facilitates mastication, moistens the food particles, makes a bolus, and assists swallowing. The movement of the jaw, and thus the neuromuscular control of chewing, plays an important role in the comminution of the food. Characteristics of the food, e.g. water and fat percentage and hardness, are known to influence the masticatory process. Food hardness is sensed during mastication and affects masticatory force, jaw muscle activity, and mandibular jaw movements. When we chew for instance a crispy food, the jaw decelerates and accelerates as a result of resistance and breakage of food particles. To understand the physiology of oral cavity, the anatomy and physiology of the teeth, masticatory muscle, temporomandibular joint, tongue, taste and saliva secretion will be discussed.
