In implant dentistry, precise measurements are incredibly important. Failure on the part of the periodontist to select the proper sizing of components for the patient can hinder healing and even contribute to the rejection of a dental implant. The actual implant length/diameter is the most exact and accurate measurement for the length and diameter of a dental implant. There are a wide variety of lengths and diameters available for a periodontist to choose from, and the optimal length/diameter of an implant depends greatly on each patient’s unique bone structure and where the implant is meant to be placed. For example, a periodontist will need to choose different lengths and diameters for implants placed in different parts of the mouth and in areas that have dense bone versus areas that have poor bone quality.
