Knowledge And Awareness Regarding Uses Of Extracted Natural Tooth In Clinical Practice, Momina Anis Motiwala, Shizrah Jamal, Karshma Devi, Rabia Ghafoor

Section of Dental-Oral Maxillofacial Surgery

Restoration of aesthetics is one the major patients’ concern in dentistry which may be disrupted due to tooth-loss secondary to trauma, or as part of orthodontic treatment or periodontal problem. A number of treatment options are available for the replacement of teeth, but they may be expensive, and time-consuming, involving artificial teeth. For immediate tooth replacement, patient’s own intentionally extracted or unintentionally avulsed tooth maybe used. The current narrative review was planned to discuss various techniques for the use of natural tooth pontic, which preserves the original contours, size and colour of the replaced tooth. Before using these teeth in …

Radiographic Evaluation Of The Margins Of Clinically Acceptable Metal-Ceramic Crowns, Sheikh Bilal Badar, Kamil Zafar, Rabia Ghafoor, Farhan Raza Khan

Section of Dental-Oral Maxillofacial Surgery

Objective: To radiographically evaluate the proximal marginal fit of the clinically acceptable metal-ceramic crowns.
Methods: The prospective study was conducted at the dental clinics of Aga Khan University, Karachi, from July to December 2018, and comprised metal-ceramic crowns that were evaluated prior to the cementation. Clinical examinations were conducted by seating the crown on the tooth preparation and visual assessment was done using sharp explorer along the margins. Clinically acceptable crowns were then evaluated on the bite-wing radiograph. Any horizontal or vertical inaccuracy of >0.5mm at the proximal margins was recorded as 'discrepancy'. Data was analysed using SPSS 22.

The Observation Of Relative Occlusal Forces Of Posterior Implant-Supported Fixed Prostheses In Tooth-Borne And Distal End Circumstance By Using T-Scan System : A Prospective Study, Jinjudhapak Thongdee

Chulalongkorn University Theses and Dissertations (Chula ETD)

Objectives: to assess the relative occlusal forces (ROF) of posterior implants in two different occlusion designs in tooth-borne and distal end circumstances over time using the T-scan system and to compare the marginal bone loss in those situations and designs over time. Material and methods: Twenty patients requiring single posterior or distal end implants were randomly assigned to two groups: Implant-protected occlusion (IPO) or load (LOAD). The ROFs were measured using a T-scan on five occasions. Custom-made jigs were used to collect periapical parallel x-rays. The implant platforms were used as a reference to assess marginal bone loss. Results: In …

A Comparison Of Shear Bond Strength On Human Dentin Using Acrylic Resin Cement And Self-Adhesive Resin Cements With The Use Of Universal Adhesives, Phatcha Maiwatana

Objective: To evaluate the shear bond strength of human dentin with two different phosphate-monomer containing self-adhesive resin cements, an acrylic resin cement, and the effect of universal adhesive pretreatment on human dentin. Materials and Methods: Fifty extracted human third molars with the superficial dentin exposure at the buccal side were prepared. Resin composite cylinders with 2.38 mm diameter were cemented with 5 groups of resin cements and universal adhesives: Rely X U200, Single Bond Universal Adhesive with Rely X U200, Panavia SA Luting Multi, Clearfil Tri-S Bond Universal Quick with Panavia SA Luting Multi, and Super Bond C&B. Then, the …

Skeletal Morphology And Tooth Alignment At The Maxillary Central Incisors For Immediate Implant Placement, Wita Buranathavornsom

Chulalongkorn University Theses and Dissertations (Chula ETD)

Objective: To analyze the classification of sagittal root position in maxillary central incisors and to evaluate how sagittal root position related to bone thickness, sex and age in Thai population. Methodology: Between 20 and 80 years old, a total of 308 CBCT images of the maxillary central incisor were chosen and classified into 4 classes (I-IV). On both labial and palatal sides, bone thickness was measured at the crestal, mid-root, and apex levels, as well as 4mm of bone beyond the apex. Additional measurements included bone height and the angle between dental root axis and alveolar bone axis. The difference …

Comparison Of Outcome Between Non-Submerged And Submerged Implant With Simultaneous Bone Augmentation In Esthetic Zone, Nuntapat Banomyong

Chulalongkorn University Theses and Dissertations (Chula ETD)

Objectives: To compare the dimensional changes in the buccal bone thickness of implant placement with simultaneous bone augmentation in the esthetic zone between non-submerged and submerged implants. Materials and methods: Twenty-four patients with a single edentulous area in the esthetic zone were randomly assigned into two groups which were submerged (cover screw) and non-submerged groups (healing abutment). After implant placement, the peri-implant defects were treated by simultaneous GBR. The cone-beam computed tomography (CBCT) scans were taken post-operative immediately (T0) and subsequent at 3 (T3) and 6 (T6) months after implant placement. Vertical buccal bone level (VBL) and horizontal buccal bone …

The Effect Of Crowding On The Accuracy Of 3d Printed Aligners, Tonya Spangler

Theses and Dissertations

Purpose: To evaluate the accuracy of three-dimensionally (3D) printed aligners compared to conventional vacuum-formed thermoplastic aligners with varying levels of dental crowding.

Methods: Digital intraoral scans of 10 different cases were assigned to their respective groups (n=10, each, 30 total) as follows: no crowding (control), moderate crowding, and severe crowding. Using 3Shape software, digital aligner samples were created in standard tessellation language (STL) file format and randomly 3D printed. The same STL files of each case were also sent to a dental laboratory for the fabrication of vacuum-formed samples, which is the current technology used for manufacturing aligners. The intaglio …
