What are 4 reasons implants can fail?

The reasons for delayed implant failure include implant overload, parafunction, and peri-implantitis.

Dental implants

can fail for a variety of reasons, but the most common, and the most preventable, are infections and bone loss. Implants can repeatedly fail in the same site due to overload, infection, and other unspecified reasons. The patient's age and sex and the location of the implant placement appear to be associated with recurrent failure.

The type of implant, the bone augmentation and the bone materials used are less relevant. A 5 × 10 mm Superline implant was placed and the healing abutment was connected, with a primary stability ISQ of 70 measured with an Osstell Mentor (Fig. Because of these unpredictable surgical situations, I suggest that patients considering implants be realistically informed that more than 90% of implants work very well for several years, but some begin to have peri-implantitis or other problems after approximately 10 years. In 3 cases (21.4%), the treatment plan was modified to include an implant bridge, while in the other 11 cases it underwent another implant placement procedure (78.6%).

In cases where a gum infection causes implants to fail (called peri-implantitis), treatment may simply consist of cleaning the implant and focusing on improving oral hygiene practices in the future. This incidence is more common among inexperienced dental implant dentists or when the dentist does not use treatment planning as part of their consultation. Osseointegration is a term used to describe the development of the structural link between bone and the newly inserted titanium implant. The final progress of the implant was confirmed by the presence of complications or unusual findings in the last observation.

One of the most challenging aspects of implant dentistry is positioning the implant so that it is completely surrounded by bone. Every effort should be made to preserve restorable natural teeth before removing them and placing implants. Initial implant failures are due to the failure of the initial osseointegration between the surface of the implant and surrounding bone due to the change in the treatment plan. The treatment methods were divided into sleep, immediate reimplantation, delayed reimplantation and absence of implantation.

One of them is located in the anterior area of the smile, where immediate implant placement can often provide better papilla retention. The objective of this study is to analyze the reasons for the recurrent insufficiency in the same site and the results of the reimplantation. TiUniteTM (Nobel Biocare, Brønemark System, Holding AG, Gothenburg, Sweden) is a system that controls roughness by machine cutting the upper part of the implant and increasing the oxide film by processing titanium oxide surfaces as it moves downward. However, the success or failure of your dental implants depends on a variety of factors, many of which are under your control.

Although the survival rate was low due to repeated implant failure in some patients, the surviving implants survived an average of 66.8 ± 51.3 months without any complications, except for slight marginal bone loss.
