Rehabilitation Of A Patient With Single Complete Tooth-Supported Overdenture Against The Unmodified Natural Dentition Using Functionally Generated Path Technique: A Case Report, Akanksha Shinde, Nilesh Bulbule, Varun Bhatt, Gayathri Balachandran, Amit Jagtap

International Arab Journal of Dentistry

Meyer’s proposed chew-in technique also called functionally generated path (FGP) technique, is indicated for the restoration of an edentulous arch that is opposed by natural teeth as it does seem to provide the most accurate method of recording occlusal patterns, also help to minimize the effects of negative factors, and to overcome the deficiencies of articulators. As stated by Rudd and Morrow, this technique is especially suitable for tooth-supported complete dentures, due to inherent stability of tooth-supported record bases helps in recording jaw relationships accurately. Whenever a single complete denture is opposed by natural dentition, problems observed are abrasion of …

การปิดสีโดยใช้ชนิดเรซินคอมโพสิตและความหนาที่แตกต่างกัน, กชรัตน์ นันทเสน

Chulalongkorn University Theses and Dissertations (Chula ETD)

ความสวยงามในเรื่องสีของฟันเป็นสิ่งหนึ่งที่ผู้ป่วยให้ความสำคัญเมื่อมารับการรักษาทางทันตกรรม โดยการเปลี่ยนสีฟันด้วยสิ่งบูรณะฟันโดยตรง ซึ่งเป็นการบูรณะฟันโดยตรงในช่องปากโดยใช้เรซินคอมโพสิต เป็นทางเลือกในการรักษาที่มีความนิยมมากขึ้น เนื่องจากมีการทำอันตรายต่อฟันน้อยที่สุด แต่ความสามารถในการปิดสีของเรซินคอมโพสิตอาจมีความแตกต่างกันไปตามแต่ละชนิด ถ้าสามารถเลือกชนิดของเรซินคอมโพสิตที่ปิดสีได้ดีในความหนาที่น้อย ก็จะช่วยลดการสูญเสียโครงสร้างฟันได้ งานวิจัยนี้จึงมีวัตถุประสงค์เพื่อเปรียบเทียบสีภายหลังการบูรณะด้วยชนิดของเรซินคอมโพสิตที่แตกต่างกัน โดยการนำเรซินคอมโพสิต 3 ชนิด ได้แก่ เคลียร์ฟิลเอพีเอ็กซ์, เมต้าฟิลซีเอ็กซ์ และฟิลเท็คซีทูไฟว์ซีโร่ ที่มีความหนา 4 ระดับ ได้แก่ 0.5, 1, 1.5 และ 2 มิลลิเมตร มาเปรียบเทียบความสามารถในการปิดสี โดยวัดด้วยตามนุษย์และเครื่องสเปกโทรโฟโตมิเตอร์ และประเมินความแตกต่างโดยใช้การทดสอบแบบครัสคัล-วอลลิสและการวิเคราะห์ความแปรปรวนทางเดียว ผลการศึกษาพบความแตกต่างอย่างมีนัยสำคัญทางสถิติที่ระดับความเชื่อมั่นร้อยละ 95 ระหว่างกลุ่มเรซินคอมโพสิตและความหนาที่ต่างกัน กล่าวโดยสรุป เรซินคอมโพสิตชนิดเมต้าฟิลซีเอ็กซ์มีความสามารถในการปิดสีเข้มสุด A6 ได้ดีกว่าเรซินคอมโพสิตชนิดเคลียร์ฟิลเอพีเอ็กซ์และฟิลเท็คซีทูไฟว์ซีโร่ในทุกระดับความหนา โดยเรซินคอมโพสิตชนิดเมต้าฟิลซีเอ็กซ์ที่ความหนาประมาณ 1.5 – 2 มิลลิเมตร สามารถบูรณะฟันสี A6 ให้ได้สีฟันที่ระดับ A1

The COVID-19 pandemic, declared by the WHO on May 2020, has forced governments around the world to adapt several restrictive measures causing difficulties of access to oral healthcare. In Lebanon, a lack of data on these difficulties and their consequences for completely edentulous people prompted the realization of a pilot study evaluating the impact of this pandemic on access to oral healthcare and on the oral health status, oral health-related quality of life (OHRQoL), and nutritional status of these individuals. The study was conducted at the Removable Prosthodontics Department of the Faculty of Dentistry at Saint-Joseph University of Beirut through …

Prosthetic Management Of Interruptive Mandibular Defects, Saloua Hamzaoui, Mohamed Azhari, Hasnaa Rokhssi, Majid Sakout, Oussama Bentahar

International Arab Journal of Dentistry

Mandibular substance loss is one of the most frequent acquired defects of the maxillofacial mass. Several etiologies have been described, the most frequent of which are tumours and traumas. The most commonly used prosthetic classification takes into consideration the bone continuity of the mandible, thus there are marginal defect mandibular substance preserving bone continuity and segmental defect with basal bone discontinuity. These bone defects lead to numerous functional complications (loss the dental occlusion, decreased chewing efficiency, lack of stalling during swallowing, phonatory disorder related to the change in the buccal resonance cavity) and aesthetic complications (facial asymmetry due to lateral …

An Overview Of Maxillofacial Rehabilitation For The General Dentist, Vladimir Frias Dds, Ms

The New York State Dental Journal

The rehabilitation of the maxillofacial patient is mostly carried out in a multi-specialty treatment environment such as a comprehensive cancer center, where multiple specialists are available to treat the numerous concerns and complications that may occur. Many of these patients are seen by the maxillofacial prosthodontist at the same time as the other members of the team and maxillofacial rehabilitation can be treatment planned and performed expediently. Some patients, however, are treated without rehabilitation in mind and go years without appropriate referrals. A knowledge of the multiple types of prostheses available will allow the general practitioner to decide if a …
