Correlation Between Maxillary Morphology And Sinus Dimensions In Skeletal Class I, Ii, And Iii Subjects: A Comparative Study, Nida Shaikh, Dipti Shastri, Pradeep Tandon, Gyan Prakash Singh

Journal of Dentistry Indonesia

Background: This study aimed to evaluate variations in maxillary and sinus morphology and their correlations with skeletal malocclusion patterns using CBCT.

Methods: This retrospective study analyzed CBCT records of 70 subjects aged 17–40 years, divided into three groups: Skeletal Class I (N = 25), Class II (N = 25), and Class III (N = 20). Five maxillary skeletal and four sinus parameters were assessed. Intergroup comparisons were performed using one-way analysis of variance (ANOVA) followed by Tukey’s post hoc test. Correlations were evaluated using Pearson’s correlation test. Intra-observer reliability was assessed by re-measuring 8 randomly selected CBCT scans …

Pterygoid Implant-Retained Bridge Following Multiple Failed Alveolar Implants In Posterior Maxilla, Kouder Dakhallah Dds, Anish Gupta Dds, Joey Wilmot, Brian Giammalva Dds

The Journal of the Michigan Dental Association

The replacement of multiple teeth with dental implants in the posterior maxilla is challenging due to factors including low density bone and sinus morphology. When considering restoration of this region, prosthetic design will dictate implant placement. Additionally, planning must consider spacing between adjacent implants, spacing between implants and adjacent teeth, and irregular alveolar ridge morphology. These key measurements translate to the final prosthesis design and will affect cleanability and future oral hygiene maintenance. These characteristics subsequently affect overall longevity of the implants and prosthesis.

In the following case, multiple closely-placed implants presenting with poor cleanability consequently failed, requiring removal and …

Randomized, Placebo-Controlled Pilot Study Of Naproxen During Dental Implant Osseointegration, Hattanas Kumchai, Daniel Taub, Ryan Tomlinson

Department of Oral and Maxillofacial Surgery Faculty Papers

OBJECTIVES: Nonsteroidal anti-inflammatory drugs (NSAIDs) are often prescribed following the placement of dental implants, but the effects of these drugs on the osseointegration process are poorly understood. We designed a randomized, placebo-controlled pilot study to quantitatively assess the effect of NSAIDs during early implant osseointegration.

MATERIALS AND METHODS: Subjects receiving a maxillary dental implant were randomized to take naproxen or placebo for 7 days after the surgery. Implant osseointegration was quantified using Resonance Frequency Analysis device. Implant-Stability-Quotient (ISQ) measurement was performed at the time of surgery and at follow-up visits 1, 4, and 16 weeks after surgery. Periapical radiographs were …

Radiographic Assessment Following Maxillary Bone Augmentation Using Patient Specific Titanium Meshes Loaded With Bone Marrow Aspirate Mixed With Xenograft Versus Xenograft Mixed With Autografts Only: A Randomized Clinical Trial, Moataz Bahaa Dr., Ahmed Moustafa Abdelmaksoud Dr., Mohamed Mounir Dr., Yasmin Nassar Prof

Dentistry

Aim: The aim of the study is to evaluate the efficacy of three-dimensional bone augmentation in maxillary atrophied alveolar ridges by comparing the utilization of bone marrow aspirate concentrate along with a mix of autograft and xenograft versus autograft and xenograft alone. utilizing patient-specific titanium meshes. Subjects and methods: Ten patients experiencing severe vertical and horizontal deficiencies in the entire maxillary arch underwent guided bone regeneration. Utilizing specialized software, virtual bone augmentation were performed for the deficient ridge across the entire maxillary alveolus. This process involved generating virtually augmented models to guide the preoperative prebending of titanium meshes. In the …

Toward Electrical Impedance Sensing Surgical Drill For Tissue Boundary Detection, Harshavardhan Devaraj

Dartmouth College Ph.D Dissertations

Dental implantation is an increasingly common procedure used to treat missing teeth. However, surgical drilling to place the implant poses a high risk of injury to critical anatomy, such as inferior alveolar nerve injury or maxillary sinus perforation. A real-time surgical feedback system sensing proximity of these critical anatomy could reduce injury risks. This dissertation investigates the development of such a system that incorporates an electrical impedance sensor into the tip of a surgical drill.

A simulation framework based on finite element method (FEM) was developed to optimize the sensor as it approached a high impedance boundary. The accuracy of …

Primary Oral Myiasis Of Anterior Maxilla In An Intellectually Disabled Female – A Case Report, Sridhar M, Shivayogi Charantimath, Anjana Bagewadi, Lokesh Kumar S, Arun Panwar, Jayapriya T, Vaishali Keluskar

Journal of Dentistry Indonesia

“Myiasis” is a term used to represent invasion caused by fly larvae that affect organs and tissues of human beings and feeds on the host tissue. It is a rare and non-specific pathology that varies according to the species of fly larvae and the area of the body involved. Various factors like extraction wounds, uncontrolled diabetes, necrotic tissues, alcohol addiction, poor oral hygiene, immunocompromised conditions and people with special care needs like debilitated or mentally challenged individuals predispose to develop myiasis. We hereby report a case of oral myiasis of the maxillary anterior region of the palate and labial mucosa, …

Assessment Of Anterior Alveolar Bone Graft Healing With And Without Coverage, With Collagen Membrane, Mary Magdy Awad Alla Abdou

Future Dental Journal

Objective

This study was designed to evaluate the retromolar as a new donor site and its ability to augment the alveolar ridge horizontal and/or vertical defects prior to implant placement.

Method

Twelve patients were selected for future implant placement after anterior maxillary ridge augmentation. CBCTs were performed preoperative, immediate postoperative and 6 months postoperative. After induction of general anesthesia, an envelope flap full mucoperiosteal flap was raised to expose the maxillary alveolar ridge defect. A donor site full thickness flap was elevated to expose the lateral body of the ramus, The graft was fixed in all the twelve patients but …

Effects Of Ectodermal Dysplasia On The Maxilla: A Study Of Cone-Beam Computed Tomography, Beyza Karadede Ünal

Makara Journal of Health Research

Background: This study aimed to examine the effects of ectodermal dysplasia (ED) on the transverse width of the maxillary bone.

Methods: The ED group was composed of seven people, while the control group consisted of retrospective cone-beam computed tomography images of seven individuals with skeletal class 1 relationship. Images on the sagittal planes were taken, and cross-sections were taken from the longest point of the Anterior Nasal Spine-Posterior Nasal Spine line. The distance between the distal anterior canine teeth from the right buccal cortical bone to the left buccal cortical bone was measured. At the posterior region, the …

Craniofacial Analysis May Indicate Co-Occurrence Of Skeletal Malocclusions And Associated Risks In Development Of Cleft Lip And Palate, Denise K. Liberton, Payal Verma, Konstantinia Almpani, Peter W.

Non-syndromic orofacial clefts encompass a range of morphological changes affecting the oral cavity and the craniofacial skeleton, of which the genetic and epigenetic etiologic factors remain largely unknown. The objective of this study is to explore the contribution of underlying dentofacial deformities (also known as skeletal malocclusions) in the craniofacial morphology of non-syndromic cleft lip and palate patients (nsCLP). For that purpose, geometric morphometric analysis was performed using full skull cone beam computed tomography (CBCT) images of patients with nsCLP (n = 30), normocephalic controls (n = 60), as well as to sex- and ethnicity- matched patients with an equivalent …
