Factors affecting the early failure of implants placed in a dental practice with a specialization in implantology – a retrospective study

摘要

To evaluate early failure and possible risk factors for failure of dental implants placed under practice-based conditions. To clarify the research question, anonymized data from 106 patients with 186 dental implants were analyzed. The presence of sucessful healing (yeso) at the time of incorporation of the final prosthesis was assessed. Mixed models were compiled for each target variable to enable estimation of the effects of patient-related and implant-related conditions on the risk of early implant failure. Nine out of 186 implants (4.8%) placed in 106 participants failed before incorporation of the final prosthesis. The use of shorter implants (?10?mm) and the need for augmentation procedures were associated with a greater risk of early implant failure. For shorter implants, the risk was 5.8 times greater than that for longer implants (p?=?0.0230). Use of augmentation procedures increased the risk by a factor of 5.5 (p?=?0.0174). Implants placed in the dental practice with a specialization in implantology heal successfully. The use of augmentation procedures and of implants shorter than 10?mm seems to be associated with a greater risk of early implant failure.
