Dental Implantology

Transplantation and implantation methods are being used more often in medicine. The same situation is in dentistry. Despite some terminological discrepancies, the term transplantation means transfer of an organ, a tissue that becomes a part of an organism, not only by its configuration and function, but also gets integrated into a recipient organism by its composition and metabolic processes - it maintains its vitality. The term transplantation also means such a transfer of precisely configured material or artificial organ that fully or partially integrates into an organism’s function, it is fully biologically tolerated but it is not vital. During last several decades, such a method - method of implanting - has begun to be more intensely utilized for repairs of a defective, incomplete dentition by means of dental implants. The term dental implant means a construction (part) of various forms or shapes which forms an artificial abutment after being inserted into the upper or lower jaw alveolus. Thus implanted artificial abutments allow for more sophisticated denture to be made in cases where teeth replacement would not otherwise be possible. It enables a person to utilize his/her teeth fully with all its functions - processing food, speech and articulation.

Variety of dental implants have been developed so far, differing in materials used, shapes, forms, ways of implanting them into jawbones and their relation to tissues. As our knowledge increases, periods of greater or smaller utilization or refusal of dental implants at clinical practice alternate.

At present times when high technology is possible and social demands increase, dental implantology is again a hot topic. Many authors have been involved in solving problems related to quite wide area of dental implants. Their opinions and results of their work have been a subject of many discussions and publications. The major problems of both foreign and domestic literature are related to materials, forms and shapes of implants, methods of implanting, availability, including suitable instrumentation, and also a very important question of biological tolerance of dental implants. This question is even more amplified by the specific property of dental implants - they penetrate the oral mucosa and stretch out freely into the oral cavity (open implants). In 1979, the FDI (Federation Dentaire Internationale) dealt with the question of biological tolerance and issued recommended international norms for dental implants materials. In Czech republic, these norms have been respected since 1986.

During last couple of decades, the worldwide field of dental implants has reached such degree of quality, especially due to scientific achievements, that it occupies a firm place at specialized extended dental care.
