Lip repositioning.

Excessive gingival display is a frequent finding that can occur because of various intraoral or extraoral etiologies. This report describes the use of surgical lip repositioning technique for the management of a gummy smile associated with vertical maxillary excess and hypermobility of the upper lip. The procedure restricts the muscle pull of the elevator lip muscles by shortening the vestibule, thus reducing the gingival display when smiling.

Comparative evaluation of pre-emptive analgesic efficacy of intramuscular ketorolac versus tramadol following third molar surgery.

Pre-emptive analgesia aims at preventing the central nervous system from reaching a hyper-excitable state known as central sensitization, in which it responds excessively to afferent inputs. The clinical implication would be more effective pain management, thereby reducing post-operative pain and analgesic requirements. This study aimed at investigating the existence of pre-emptive analgesia and to compare the pre-emptive analgesic efficacy of im ketorolac [NSAID] versus tramadol [SYNTHETIC OPIOD] for post-operative pain management following third molar surgery.

Efficacy of buprenorphine added 2 % lignocaine 1:80000 in postoperative analgesia after minor oral surgery.

Purpose: Recent studies have demonstrated that opioid analgesia cannot be exclusively attributed to effects within central nervous system. Peripheral opioid receptors exist that can be activated by locally applied opioid agonists which mediate analgesic effects that are particularly prominent in painful inflammatory conditions. Patients who present themselves with conditions requiring minor surgery in the maxillo-facial region usually have associated ongoing inflammatory process.

Magical NiTi expander.

A 24-year-old male patient was referred to our department for expansion of the constricted maxillary arch as a presurgical procedure for the correction of congenital facial disfigurement. On examination, the patient had a convex profile, increased interlabial gap, tongue thrust, limited mouth opening, posterior crossbite, asymmetric 'V'-shaped maxillary arch with severe constriction, crowding of anterior teeth in the maxillary arch and a massive open bite. Radiographic investigations included orthopantomograph and occlusal radiographs.

Transmigration of mandibular canines.

The purpose of this paper is to present the first case of unusual reverse oblique (110 degrees to midsagittal plane) migration of mandibular right canine crossing the jaw midline and piercing the lower border of the mandible at the level of the opposite canine and also to report two more cases of transmigrated mandibular canine and one case of transmigrating mandibular canine. Mandibular canines are "cornerstone" of dental arch; their importance is manifested by their efficiency in masticatory function, stability of dental arch, and aid in maintaining natural facial expression. Early detection of this anomaly can help preserving these canines by orthodontic intervention or by surgical transplantation.

Bifid mandibular condyle.

A 20-year-old young male patient presented with limited mouth opening and cosmetic disfigurement since childhood. On examination, marked mandibular hypoplasia resulting in a convex facial profile was noted. Further radiographic investigation using orthopantomograph and CT scan with three-dimensional reconstruction revealed bifid mandibular condyle of the right side.

Intraosseous schwannoma of the mandible.

Schwannomas (neurilemmomas) are slow-growing, benign neoplasms derived from schwann cells, the sheath cells that cover myelinated nerve fibers. These tumors most commonly arise in the soft tissues of the head and neck, as well as on the flexor surfaces of the upper and lower extremities. Intraoral lesions are uncommon, however, and intraosseous schwannomas are even rarer.

Presurgical management of a child with missing lower lip using a new design of fixed lower tongue crib.

Missing of any perioral structure can result in imbalance of muscular forces leading to loss of structure and function along with esthetics especially in a growing individual and can result in permanent damage. Rehabilitation of such children is a challenge and requires an integrated multidisciplinary approach not only to correct the defect, but also to ensure normal development with minimal handicap. Here is a case report of a 10-year-old child with missing lower lip due to childhood infection and its presurgical management using a new design of fixed lower tongue crib used to limit tongue pressure, improve tongue position, and facilitate lower incisor retraction.
