Aim This in vitro study aimed to evaluate the effect of implant impression coping geometrical designs on the accuracy of open and closed impression techniques and in the parallel and nonparallel implant positions. Material and methods Three custom-made acrylic resin models of three tested implant systems (Straumann (R), SIC Invent (R), and Osstem (R)) with diverse coping geometrical designs were evaluated in simulated cases of two parallel and two nonparallel implants. The horizontal and vertical discrepancies were measured and analyzed. Results No statistically significant differences between the two impression techniques in either parallel or nonparallel implants were observed. The high …

Non-syndromic orofacial clefts encompass a range of morphological changes affecting the oral cavity and the craniofacial skeleton, of which the genetic and epigenetic etiologic factors remain largely unknown. The objective of this study is to explore the contribution of underlying dentofacial deformities (also known as skeletal malocclusions) in the craniofacial morphology of non-syndromic cleft lip and palate patients (nsCLP). For that purpose, geometric morphometric analysis was performed using full skull cone beam computed tomography (CBCT) images of patients with nsCLP (n = 30), normocephalic controls (n = 60), as well as to sex- and ethnicity- matched patients with an equivalent …


Pink Tooth Of Mummery In The Maxillary Left Canine After Fixed Partial Denture (Fpd) Preparation, Eger V. Korolevsky, Takashi Komabayashi, Denise Foran Nov 2019

Pink tooth of Mummery is typically found after trauma. However, this case report describes an unusual occurrence of pink tooth in a 67-year-old Caucasian male after fixed partial denture (FPD) tooth preparation. Pink tooth in this case may be due to one or more factors: tooth reduction and heat generation during tooth preparation; heat generation during polymerization of provisional material; and hyperocclusion of a provisional FPD. This case highlights the importance of choosing the appropriate materials and techniques to avoid pulpal complications after dental prosthesis work.

Managing Peri-Implantitis, Namita Khandelwal

Dental Medicine Faculty Publications

This guide, used by MetLife for its dental continuing education program, focuses on the inflammatory pathology around dental implants. It outlines the risk factors and diagnostic criteria for peri-implantitis, an inflammatory process resulting in progressive loss of bone around the implant. The guide also provides treatment approaches for peri-implantitis, including surgical and non-surgical options.
