Radiological Evaluation of Anterior Maxilla For Immediate Implant Placement
An observational study of Maxillary Retrusion, run by TC Erciyes University at 2 sites in Turkey (Türkiye).
Trial summary
According to the literature age and gender may be associated with differences in skeletal size, anatomy and architecture in humans. However, little is known about the synergistic effects of age and gender on the healing capacity of maxillary bones, since most of the preclinical studies are focused on each variable… Read more about this study

About this study
Official title: Evaluation of Buccal Bone Thickness, Ridge Dimensions, And Root Position In Anterior Maxilla For Immediate Implant Placement
According to the literature age and gender may be associated with differences in skeletal size, anatomy and architecture in humans. However, little is known about the synergistic effects of age and gender on the healing capacity of maxillary bones, since most of the preclinical studies are focused on each variable separately. The present study radiologically evaluated various parameters such as alveolar crest height and width, buccal bone thickness, degree of buccal undercut, and root-crest angle using cone-beam computed tomography (CBCT) in a large patient population, and compared these parameters across different age and gender groups to analyze the effect of aging and gender on the bone morphology in the anterior maxillary region.
Read the detailed description
Aim: The aim of this present study was to radiologically evaluate the socket morphology that may have a clinical impact on the outcomes of immediate implant placement in the anterior maxilla, using cone-beam computed tomography (CBCT) in a large patient population. Moreover, the parameters were compared between different age and gender groups to analyze the effect of aging and gender on the bone morphology around the maxillary anterior teeth.
Material and Methods: This study evaluated a total of 1,668 teeth in the esthetic region, including bilateral central incisors, lateral incisors, and canines in the upper anterior region, using CBCT images from 278 individuals. CBCT images were grouped into age ranges of 20-29, 30-39, 40-49, 50-59, 60-69, and 70-80 years. The morphology of the anterior ridge was assessed by separately measuring alveolar ridge width and height, buccal bone thickness, tooth-crest angle, and buccal undercut for maxillary central incisors.

What participants receive

radiological evaluationOther
Using a line drawn through the midpoints of the teeth, parallel to their long axes, the anterior crest morphology was assessed. For maxillary central, lateral, and canine teeth, alveolar crest width and height, buccal bone thickness, and tooth-crest angle were measured separately. To determine buccal bone thickness, measurements were taken from the buccal crest apex, the midpoint of the root, and the apex of the tooth. The height of the alveolar crest was defined as the length of a line drawn parallel to the crest's long axis between the nasal fossa floor and the alveolar crest. The width of the alveolar crest was calculated by averaging measurements taken from the midpoints of three equal sections of the alveolar crest. The buccal undercut was determined as the point where the crest came closest to the root in the sagittal plane. Additionally, the angle between the tooth roots and the alveolar crest was measured to determine the root position in the radial plane

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Alveolar Crest Height (time frame: One year). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Aug 2025.
