AB - Statement of problem: There are no clear diagnostic guidelines for producing a mandibular implant
overdenture (IOD).
Purpose: The aim of this clinical report was to present a set of principles that can be used during diagnosis
and treatment planning for later ideal implant positioning and promotion of optimal patient-centered
outcomes.
Materials and Methods: With our novel method for determining an ideal implant position, the mandibular
arch is divided into 3 zones (Zone 1, 2, 3) according to the relationship between the alveolar crest and
artificial tooth position. Following implant placement, the patient is provided with a mandibular IOD.
At the 2-year follow-up evaluation of prostheses placed in 2 patients, the chief complaints were totally
resolved, and no complications were noted.
Conclusions: Although out findings are limited, they indicate that the present diagnostic method for
planning mandibular IOD treatment results in a good outcome. Future well-designed clinical studies are
necessary before making definitive conclusions.
