Mini implants have been improved and established as an immediate-loading implant system to retain edentulous mandibular denture for short and long term. A 3-dimensional imaging is a useful computer analysis based on the computed tomography data for implant pre-surgical planning. This clinical report describes: 1) Mini implant system enhanced support the stability of edentulous mandibular denture. 2) Preparation of the provisional over-denture together with the accurate diagnosis by 3-dimensional image could shorten the surgery and fixing time. 3) While the patient used the provisional over-denture, the proper holes for housings in the final denture could be formed at the minimum of size in the dental laboratory.
