Nasal Tip Reshaping in Orthognathic Surgery: A Novel Intraoral Minimally Invasive Approach.

Current concepts in orthognathic surgery focus on not just rectifying dentoskeletal irregularities but also improving facial aesthetic and function. In this respect, nasal reshaping holds extraordinary significance in determining surgery effectiveness and patient satisfaction. Facial preoperative evaluations emphasize the paramount functional and aesthetic impacts of caudal septum in tip reshaping.

Immediate versus conventional loading of mandibular implant-retained overdentures: a 3-year follow-up of a randomized controlled trial.

Clinical Versatility of the Facility-Equator Implant System as Mandibular Overdenture Retainers.

The use of mandibular overdentures (MO) for the rehabilitation of totally edentulous individuals with limited bone availability is widespread and has proven clinical success. Narrow diameter implants (NDI) are available on the market as MO retainers to solve problems related to limited bone availability and bone thickness, providing a low-cost, minimally invasive treatment option. This technique evolved over the years, and changes frequently involved the number of implants used as MO retainers, as the adoption of a smaller number of implants can generate biomechanical disadvantages, contributing to the increased stress in peri-implant tissues, which may accelerate marginal bone loss (MBL), in addition to reducing masticatory capacity and satisfaction with rehabilitation.
