Influence Of Free-End Distal Extension On The Accuracy Of Guided Implant Placement: An In Vitro Study, Geoffrey Ganzman
Influence Of Free-End Distal Extension On The Accuracy Of Guided Implant Placement: An In Vitro Study, Geoffrey Ganzman
Master's Theses (2009 -)
Purpose: The aim of this study was to evaluate the influence of type of tooth-support (bounded edentulous space versus unbounded edentulous spaces) on the accuracy of fully-guided implant placement using static computer-assisted implant surgery (sCAIS) in partially-dentate patients. Methods: Four different clinical scenarios were simulated; (a) bounded single-tooth edentulous space (BES), and three different free-end distal extensions with (b) unbounded single-tooth edentulous space (UBES1), (c) unbounded two-teeth edentulous space (UBES2), and (d) unbounded three-teeth edentulous space (UBES3). An implant planning software was used to design 3D-printed stereolithographic surgical guides for the respective clinical scenarios. In total n=140 implants with dimensions …

Titanium dioxide (TiO2) nanostructures are one of the most plentiful compounds that have emerged in various fields of technology such as medicine, energy and biosensing. Various TiO2 nanostructures (nanotubes [NTs] and nanowires) have been employed in photoelectrochemical (PEC) biosensing applications, greatly enhancing the detection of targets. TiO2 nanostructures, used as reinforced material or coatings for the bare surface of titanium implants, are excellent additive materials to compensate titanium implants deficiencies—like poor surface interaction with surrounding tissues—by providing nanoporous surfaces and hierarchical structures. These nanostructures can also be loaded by diversified drugs—like osteoporosis drugs, anticancer and antibiotics—and …
Peri-Implantitis Risk Prediction Using A Computer Based Periodontal Risk Calculator Tool: A Retrospective Study, Walaa Al Zaibak
Peri-Implantitis Risk Prediction Using A Computer Based Periodontal Risk Calculator Tool: A Retrospective Study, Walaa Al Zaibak
Master's Theses (2009 -)
Introduction: Although literature is abundant on the diagnosis and management of peri-implantitis after it has occurred, to our current knowledge there are no studies that have specifically looked into the relationship between peri-implantitis and the periodontal risk assessment tool used for natural dentitions.Material and Methods: In this retrospective study, the patient population included patients (>20 years of age) who had implants placed and restored at Marquette University School of Dentistry (MUSOD) from 2008 to 2016. Further, the restored implants in these patients must have been in function for at least one year and followed up in the school …
Evaluation Of Accuracy Of Static Computer-Guided Implant Placement Compared With Partially-Guided Or Free-Hand Placement, Laxmi Sukhtankar
Evaluation Of Accuracy Of Static Computer-Guided Implant Placement Compared With Partially-Guided Or Free-Hand Placement, Laxmi Sukhtankar
Master's Theses (2009 -)
Purpose: To evaluate precision and trueness of static computer-assisted implant surgery (sCAIS) in comparison with partially-guided and free-hand implant placement in vitro.Materials & Methods: The study was conducted on one hundred mandible replicas obtained from a cone beam computer tomography of a partially edentulous case for implant placement in mandibular right first molar site. First, the fully guided implant placement with different sleeve to bone distances (2mm = H2, 4mm = H4, 6mm= H6) was determined. Second, fully guided implant placement was compared with partially guided, and free implant placement. The achieved implant position was digitized and compared …
Comparing The Vertical Misfit Of Casts Produced By Two Verification Jigs, Abdulaziz Saeed Alqahtani
Comparing The Vertical Misfit Of Casts Produced By Two Verification Jigs, Abdulaziz Saeed Alqahtani
Master's Theses (2009 -)
Purpose: To compare the dimensional accuracy between master casts fabricated with verification jigs made of acrylic resin and light cure Triad. Materials and Methods: 10 GC Pattern resin Pattern verifications jigs and 10 Triad gel verification jigs fabricated of a master cast of a mandibular model of 4 internal hex implants. A stone base was fabricated for each verification jig. One screw test was used to evaluate the vertical gap at the terminal abutment using a digital micrometer with an accuracy of 1μm to record the vertical gap for each sample. Results: Triad Gel group has the lowest average distortion …

Titanium nitride and/or nitrogen ion implanted coated dental materials have been investigated since the mid-1980s and considered in various applications in dentistry such as implants, abutments, orthodontic wires, endodontic files, periodontal/oral hygiene instruments, and casting alloys for fixed restorations. Multiple methodologies have been employed to create the coatings, but detailed structural analysis of the coatings is generally lacking in the dental literature. Depending on application, the purpose of the coating is to provide increased surface hardness, abrasion/wear resistance, esthetics, and corrosion resistance, lower friction, as well as greater beneficial interaction with adjacent biological and material substrates. While many studies have …
