A dental implant is considered to be a failure if it is lost, mobile or shows peri-implant (around the implant) bone loss of greater than 1.0 mm in the first year and greater than 0.2 mm a year after. [5] Dental implant failures have been studied. [6] Persons who smoke habitually prior to having dental implants are significantly more likely to ...
Alveolar bone resorption is a common side effect of tooth removal (extraction) due to severe tooth decay, trauma, or infection that limits dental implant placement. Surgical bone augmentation is associated with limitations such as high cost, bone graft rejection or failure, pain, infection, and the addition of 6–12 months to the treatment ...
Bone grafts are used in hopes that the defective bone will be healed or will regrow with little to no graft rejection. [19] Besides the main use of bone grafting – dental implants – this procedure is used to fuse joints to prevent movement, repair broken bones that have bone loss, and repair broken bone that has not yet healed.

Bone grafting procedures in the jaws have the disadvantage of prolonged treatment time, restriction of denture wear, morbidity of the donor surgical site and graft rejection. [ 4 ] Zygoma implants were first introduced in late 1990s by Dr. Per Ingvar Brånemark , widely acknowledged as the "Father of Dental Implantology".
At present, guided bone regeneration is predominantly applied in the oral cavity to support new hard tissue growth on an alveolar ridge to allow stable placement of dental implants. When bone grafting is used in conjunction with sound surgical technique, guided bone regeneration is a reliable and validated procedure.
Socket preservation or alveolar ridge preservation is a procedure to reduce bone loss after tooth extraction. [1] [2] After tooth extraction, the jaw bone has a natural tendency to become narrow, and lose its original shape because the bone quickly resorbs, resulting in 30–60% loss in bone volume in the first six months.

Root analogue ceramic dental implant in comparison with titanium screw type implant. As technology has improved, so has implant success rate. Conventional titanium dental implants typically have success rates of 90–95% for 10-year follow-up periods, but this is based on questionable definitions of success. [5]
In cleft palate patients bone grafting during the mixed dentition has been widely accepted since the mid-1960s. The goals of surgery are to stabilize the maxilla, facilitate the healthy eruption of teeth that are adjacent the cleft, improving the esthetics of the base of the nose, create a bone base for dental implants, and to close any oro-nasal fistulas.
