The basis for modern dental implants is a biological process called osseointegration, in which materials such as titanium or zirconia form an intimate bond to the bone. [1] The implant fixture is first placed so that it is likely to osseointegrate, then a dental prosthetic is added.
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]
The head of the zygoma implant is engineered to allow prosthesis attachment at a 45-degree angle to the long axis of the implant. [7] Zygomatic implants can be used in patients who do not have any teeth in the upper jaw, patients who have heavily broken down teeth or very mobile teeth due to diseases such as generalised aggressive periodontitis ...
Structure of dental inlays and onlays In dentistry, inlays and onlays are used to fill cavities, [ 1 ] and then cemented in place in the tooth . This is an alternative to a direct restoration , made out of composite, amalgam or glass ionomer , that is built up within the mouth.
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.

The recipient site should be free from acute infection and chronic inflammation. [3] Adequacy of bone support is crucial criteria for success. [ 3 ] To ensure stabilisation of the transplanted tooth and to avoid infection there must be sufficient bone support in all dimensions with adequate attached keratinised tissue.
