Replacing A Single Tooth: Single Implant Vs. Three Unit Bridge, Ibeth Erazo, Aneeza Hussain

Publications and Research

There are more than two options for restoring a single tooth but our research includes a three-unit bridge and a single-tooth implant as the main options. In this paper, we discuss the advantages and disadvantages of these methods and the factors that must be considered when choosing between them for the replacement of a single tooth. Although in some cases a three-unit bridge is the most appropriate choice, implants have the advantage of allowing preservation of the integrity of sound teeth adjacent to the edentulous area. Many factors must be considered when choosing between a three-unit bridge and an implant …

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

Dental Medicine Faculty Publications

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.

Analysis Of Periapical Biopsies Submitted For Histopathological Evaluation: A Retrospective Study, Abdullah I. Alqaied

Master's Theses

Apical periodontitis is the most common pathological process in the periapical region. Disciplined clinical and radiographic evaluations and appropriate diagnostic tests can detect lesions related to apical periodontitis. Aside from this, lesions mimicking pulp-related pathology but unrelated to pulpal infection and necrosis are occasionally discovered in the periapical region. The objective of this study was two-fold: (1) to determine the prevalence of diverse periapically located pathological entities, and (2) to apply that information to evaluate the rationale for routine submission of surgically obtained tissue for histological examination and diagnosis. Methods: A 5-year retrospective analysis of pathology reports from the UCONN …

Loma Linda University Electronic Theses, Dissertations & Projects

Immediate provisionalization of single implants with standard (3.75 - 4.5 mm) and wide diameter (> 4.5 mm) has been well documented. When the space is limited, small diameter implants (3.0 mm) must be used. Although high success rates have been reported, they were limited to healed site and were placed as staged procedures. The purpose of this prospective study was to evaluate the success rate and peri-implant tissue response of small diameter (3.0 mm) implants undergoing immediate provisionalization in the esthetic area.

Eleven patients who had missing maxillary lateral incisor(s) and/or mandibular incisor(s) participated in this study. Thirteen 3.0 mm …
