Dental students using conventional chairs need immediate change in their posture. Implementing an ergonomic posture is necessary as they are at high risk for developing musculoskeletal disorders. This study recommends the use of an ergonomic seat and magnification system to enhance the visibility and the posture of an operator. The aim of this study is to make a foray into the hazards caused by inappropriate posture of dental students while working. It also aims at creating a cognizance about the related health implications among the dental fraternity at large, and to understand the significance of adopting an ergonomic posture since the beginning of the professional course. In the present study, postures have been assessed by using rapid upper limb assessment (RULA). This method uses diagrams of body postures and three scoring tables to evaluate ones exposure to risk factors. Ninety students from II BDS (preclinical students in the second year of dental school) were assessed in three groups using three different seats with and without magnification system. The results recorded significantly higher RULA scores for the conventional seats without using the magnification system compared to the SSC (Salli Saddle Chair-an ergonomic seat) with the use of magnification system. A poor ergonomic posture can make the dental students get habituated to the wrong working style which might lead to MSDs (Musculoskeletal diseases). It is advisable to acclimatize to good habits at the inception of the course, to prevent MSDs later in life.

Along with functions like grasping and feeling, hands also have an esthetic impact and they can emphasize the beauty of a gesture or grace of a movement Finger and partial finger amputations are some of the most frequently encountered forms of partial hand loss.Whether the traumatic loss of limb or finger is due to war, congenital malformations, systemic diseases (diabetes), an industrial, domestic or vehicular accident, amputation leaves the individual with a long lasting emotional scar from the disfigurement.The concealment of the amputation with the help of reconstructive surgery or prosthesis usage can shield an amputee from social stigma and help improve emotional healing process.Fabrication of finger prosthesis is as much as an art as it is science. The traditional techniques of prosthesis fabrication as described in the review, via silicone and osseointegrated implant for anchorage of digital prosthesis serves an alternative to complex surgical procedures.

Insufficient bone volume is a common problem encountered in the rehabilitation of the edentulous posteriormaxilla with implant?supported prostheses. Although adequate bone height can be achieved using variousmaxillary sinus augmentation techniques, these procedures have been practiced successfully. However,significant complications occur such as perforations or tearing. To maintain the integrity of Schneiderianmembrane subsequently increasing the success rate a retrospective analysis is carried out on varioustechniques with complications which occur during and after treatment. This review will help the readers tounderstand the intricacies of sinus augmentation by using direct techniques.

The bone available for implant placement may be limited by the presence of the maxillary sinus togetherwith loss of alveolar bone height and it may be increased by augmentation. Minimally invasive sinusaugmentation is an effective solution for this problem. This review explains indirect sinus augmentationprocedures which are less invasive and highly successful if done using prescribed technique.
