Relation between Bone Density and Primary Stability in the Posterior Mandibular Region in Patients Undergoing Dental Implant Treatment: A Retrospective Study.

Tooth loss has become one of the most raising issues to be brought up in dentistry, by both patients and dentists. Teeth are considered to be important in case of function and esthetics. Compromise to the dentition would raise social disturbances for the individual. Dental implants are surgical fixtures or artificial tooth roots that are placed into the jawbone. It is one of the best methods of tooth replacement. When considering implants, the dentist must approach it with a multidisciplinary treatment plan. They should consider factors such as age, gender, habit, systemic diseases, oral hygiene, placement site and technique, bone width and bone height, bone density, etc. complications for implant surgery would include bleeding, infections, pain, breakage, etc. A single center retrospective study was done in an institutional setting. The data for the study was retrieved from the college's patient records management software. All patients undergoing implant surgery in the posterior mandibular region were considered. The patients age, gender, implant site, bone width, and bone height were taken into account as variables. The data received was analyzed using SPSS. A total of 737 patients were considered in the study, 383 being male patients and remaining 354 being female patients. the right and left molar teeth were more commonly replaced in comparison to premolars. The association between the primary stability and bone density was statistically significant (p < 0.05). Within the limitations of the study, males had better bone density than females and D2 bone density was predominantly seen in both males and females and between the age group between 26 to 40 years. D2 bone density is seen in both left and right molar regions. Primary stability was associated with the implant length, width and bone density.
