Clinical experiences with dental implants.
The clinical utilization of dental implants has accelerated in recent years, and new applications continue to emerge. Concomitantly, alternative implant systems have introduced conceptually different approaches to treatment using altered protocols. The purpose of this paper is to address some of the background issues pertinent to the long-term success, survival, safety, and effectiveness of these devices. The requirements for clinical acceptance of implants are controlled initially by regulatory bodies; however, the dentist eventually must make a decision on which type of implant should be used in clinical practice. This clinical decision-making process should involve the strategy of using an evidence-based approach to ensure quality of care and reduction of liability for negligent care. This is particularly the case when treatment is undertaken in identified high-risk categories. While short- to medium-term data have been accumulated on the success rates of several implant systems, it is apparent that long-term data comparing and contrasting the various advantages and disadvantages of different systems do not exist, and adequate criteria applicable to the collective clinical experience need to be defined. Expanding areas of application are dependent on continuous improvements in implant hardware, surgical protocol development, and rationalized osteopromotive and site installation augmentation technology. Many treatment endeavors are still largely at the pilot study level of development, and long-term prospective clinical trials on large numbers of patients are required to document results adequately and to elucidate the most likely productive areas for future investigation.
