The influence of implant platform apico‐coronal position on the bone level of adjacent teeth

This study looked at how the vertical position of a dental implant affects the bone levels around nearby natural teeth, especially in the front and premolar areas of the mouth. Our team reviewed records from 96 patients who received a total of 117 implants. We measured the distance between the top of each implant and the bone level of the teeth next to it. The implants were grouped into two categories: those placed 2 millimeters or less below the bone level of nearby teeth, and those placed more than 2 millimeters below. The results showed that when implants were placed more than 2 millimeters below the nearby teeth, there was more bone loss around those natural teeth over time. This was especially true when the implant crown had a rounded (convex) shape at the gumline and in female patients. However, when the implant was placed closer to the bone level (≤2 mm) of the adjacent teeth, the amount of bone loss was smaller and less affected by the crown shape. Dentists should carefully consider how deep they place implants in relation to the surrounding teeth. Placing implants too far apical of the bone level of nearby teeth may lead to unwanted bone loss in those teeth, especially if the implant crown has a rounded (convex) profile. Proper implant positioning can help to reduce the risk of bone loss and improve long-term outcomes.
