Surgery-first approach (SFA) has been a paradigm shift in the field of orthognathic surgery. Majority of the published cases that have been managed by this approach are of skeletal class III. This communication describes a patient of 18-year-old male diagnosed with skeletal class II malocclusion due to mandibular retognathism. He was managed with SFA and was using skeletal anchorage system to prevent postsurgical relapse. Bilateral saggital split ramus osteotomy was carried out to achieve the mandibular advancement of 7 mm. Using this approach good esthetic result, functional occlusion was achieved. Patients were benefited with marked improvement in profile at a very early stage of treatment and shorter total treatment time of about 7 months.

Introduction: Prolonged orthodontic treatment duration is detrimental in terms of increased incidence of caries, root resorption, and reduced patient compliance. The aim of this randomized, clinical trial was to evaluate the effect of low-level laser therapy (LLLT) on the rate of orthodontic tooth movement (OTM) and pain control. Materials and Methods: This single-blind study included twenty participants requiring extraction of all first premolars. Randomly selected split-mouth design was used. One side was irradiated with 810 nm diode laser (dose of 5.0 J/cm 2) at 10 points for 10 s. Irradiation was performed just after loading canine retraction forces and on days 3 rd and 7 th. Every 21 st day, the force level of coil spring was adjusted, and LLLT protocol was repeated till retraction was complete. Measurements were recorded on study models to evaluate the rate of retraction. Results: Significant increase in OTM was observed on the side exposed to LLLT when compared to control side (P < 0.05). Statistically significant difference in pain perception was observed during first 2 days only between lased site and control site (P < 0.05). Conclusion: LLLT is a reliable tool for enhancing OTM and is effective in relieving pain at parameter settings and protocol used in this study.

Fixed partial dentures (FPDs) with high-strength all-ceramic systems are necessary for replacing missing teeth. Wide range of materials and methods are available to fabricate a restoration outside the mouth and subsequently integrate with a tooth. The traditional methods of ceramic fabrication have been described to be time-consuming, technique sensitive, and rather unpredictable due to the many variables present which affect the outcome. All-ceramic restorations, has become a segment of dentistry which has experienced tremendous improvements in the recent years. The increasing use of polycrystalline alumina and zirconia as framework materials and the increasing popularity and variety of computer-aided design and computer-aided manufacturing (CAD-CAM) systems seem to be mutually accelerating trends over the last three decades. This article presents a review of the development of all-ceramic restorations, including the evolution and development of materials, technologies and how to improve the strength of all-ceramic restorations, with respect to survival, applications, strength, color, and aesthetics. The literature demonstrates that multiple all-ceramic materials and systems that are currently available for clinical use and concludes there is not a single universal material or, system available to suit for all clinical situations.
