Extraoral Maxillofacial Prosthesis Implant Retention Systems: A Critical Review., Hugh Byrne, Marina L. Pimentel
Extraoral Maxillofacial Prosthesis Implant Retention Systems: A Critical Review., Hugh Byrne, Marina L. Pimentel
Articles
Objectives: The purpose of this literature review is to provide information on the different available techniques for implant-supported prosthetic retention, which are bar-clip, o-ring or magnets. Through presenting the practitioner preferences reported in literature, although limited from strict comparison due to the heterogeneity of methodologies and studied individuals, this review aims to identify the choices for maxillofacial prosthesis implant retention systems, regarding patient comfort and good aesthetic outcome, as an aid to surgical and prosthetic planning for implant-supported extraoral maxillofacial prosthetics. With proper knowledge of each implant retention system, a practitioner can design a treatment plan which allows for a …
Expression Of Human Tissue Kallikreins (Klks) In Polymorphous Low Grade Adenocarcinoma (Plga), Jacqueline M. Cox
Expression Of Human Tissue Kallikreins (Klks) In Polymorphous Low Grade Adenocarcinoma (Plga), Jacqueline M. Cox
Electronic Thesis and Dissertation Repository
Polymorphous low grade adenocarcinoma (PLGA) is the second most common malignant salivary gland tumour of the minor salivary glands. Human tissue kallikreins (KLKs) are a family of highly conserved serine proteases expressed by various tissues throughout the body. KLKs have become powerful tumour markers for the diagnosis of the cancer patient (e.g. PSA (KLK3)). The literature demonstrates a link between KLKs and salivary gland neoplasms. The purpose of this study is to determine levels of KLK mRNA in tissue samples of formalin fixed paraffin embedded polymorphous low grade adenocarcinoma (PLGA). Secondly, we wish to determine if KLK expression is limited …

Faculty Research, Publications, and Presentations
Purpose: Preclinical and clinical studies have shown that marginal bone loss can be secondary to repeated disconnection and reconnection of abutments that affect the peri-implant mucosal seal. The aim of this systematic review and meta-analysis was to evaluate the impact of abutment disconnections/reconnections on peri-implant marginal bone level changes.
Materials and Methods: To address this question, two reviewers independently performed an electronic search of three major databases up to October 2015 complemented by manual searches. Eligible articles were selected on the basis of prespecified inclusion and exclusion criteria after a two-phase search strategy and assessed for risk of bias. A …
Orofacial Pain Overview: Getting Rid Of The Riddles, Andrew L. Young
Orofacial Pain Overview: Getting Rid Of The Riddles, Andrew L. Young
Andrew L. Young
While most pains that find their way to the dental office are dental in origin, some have less familiar roots: muscular, joint, neurological, headache, sinus or psychological. All of these roots can at times masquerade as a toothache. The purpose of this article is to alert the dentist to the select features of each root that distinguish it from the rest, resulting in efficient and appropriate treatment.
Comparison Of The Accuracy Of Surgical Guided Template Produced From Intraoral Scan Technique And Model Scan Technique For Implantation Using Computer Assisted Implant Surgery, Prudsaporn Kiatkroekkrai
Comparison Of The Accuracy Of Surgical Guided Template Produced From Intraoral Scan Technique And Model Scan Technique For Implantation Using Computer Assisted Implant Surgery, Prudsaporn Kiatkroekkrai
Chulalongkorn University Theses and Dissertations (Chula ETD)
Objectives: To compare the accuracy of implant position placed by CAIS technique using surgical guided template produced by intraoral scan and model scan. Materials and methods: Patients who needed single tooth implant restoration were enrolled in this study and devided into two groups randomly according to the surface scan technique (n=30 each group). Intraoral scans were done using the Trios Scanner (3shape). While, diagnostic casts were scanned by D900L lab scanner (3shape). The templates were design by the clinician using coDiagnostiX software (Dental Wings Inc.). Implant surgery were performed according to fully CAIS protocol. CoDiagnostiX software was used to compare …
In Vitro Effect Of L-Ascorbic Acid On Gingival Fibroblast To Regulate Wound Healing., Tatcha Chaitrakoonthong
In Vitro Effect Of L-Ascorbic Acid On Gingival Fibroblast To Regulate Wound Healing., Tatcha Chaitrakoonthong
Chulalongkorn University Theses and Dissertations (Chula ETD)
Background and Objective: Besides closing the wound by intrinsic properties like migration and proliferation, gingival fibroblasts produce a major source of extracellular matrix especially collagen and play a major role in oral wound healing. Vitamin C or L-ascorbic acid has diverse functions in the body, including an essential role in hydroxylation reactions which is necessary for collagen formation. Whether L-ascorbic acid can promote gingival wound healing through inducing proliferation of fibroblasts is of our interest. The aim of this study is to evaluate the effect of L-ascorbic acid on gingival fibroblasts behaviors to promote wound healing in vitro. Materials and …
Comparative Study Of In Vivo Bone Regeneration Using Chitosan/Dicarboxylic Acid Scaffold Implanted With Human Periodontal Ligament Cells, Teerawat Sukpaita
Comparative Study Of In Vivo Bone Regeneration Using Chitosan/Dicarboxylic Acid Scaffold Implanted With Human Periodontal Ligament Cells, Teerawat Sukpaita
Chulalongkorn University Theses and Dissertations (Chula ETD)
After tooth loss, a consequent atrophy of the alveolar process always takes place and adversely affect the reconstruction process especially by dental implant. A novel chitosan/dicarboxylic acid scaffold (CS/DA scaffold) has been developed and proven to be an excellent candidate material in bone tissue engineering. This study aimed to evaluate the effects of a CS/DA scaffold with and without seeded primary human periodontal ligament cells (hPDLCs) in mouse calvarial defect model. Eighteen mice were divided into 3 groups of 6 each. Four-millimeter calvarial defects were created on both side of parietal bone and implanted with either CS/DA scaffold or CS/DA …
Patient's Perception And Satisfaction On Dental Implant Therapy By Postgraduate Dental Students And Experienced Dentists, Pat Vipattanaporn
Patient's Perception And Satisfaction On Dental Implant Therapy By Postgraduate Dental Students And Experienced Dentists, Pat Vipattanaporn
Chulalongkorn University Theses and Dissertations (Chula ETD)
Objective: To evaluate and compare patient's perception and satisfaction between patients who received dental treatment from postgraduate dental students and experienced dentists. Material and methods: This descriptive cross-sectional study was performed in patients who received the dental implant from Faculty of dentistry Chulalongkorn University. A data collection of patient's perception and satisfaction was done by questionnaire which was sent by mail. The questionnaire contained 23 statements including 7 statements of demographic data, 7 statements of perception, and 9 statements of satisfaction. The patient had to answer through the one-best-answer multiple choices and visual analog scale (VAS). Results: The 382 participants …
