Patients wearing complete dentures for a long time usually exhibit lack of bone and keratinized mucosa in the bearing area due to bone resorption. The patients suffering from this phenomenon usually have unstable and non-retentive complete denture, which result in constant trauma to the mucosa, pain, functional limitations and worsening of facial esthetics. An innovative technique has been desc...

PURPOSE The purpose of this animal study was to perform a 3-dimensional micro-computed tomography (micro-CT) analysis in order to investigate the influence of root surface distance to the alveolar bone and the periodontal ligament on periodontal wound healing after a guided tissue regeneration (GTR) procedure. METHODS Three adult Sus scrofa domesticus specimens were used. The study sample inc...

Two case reports demonstrate a new orthodontic method that offers short treatment times and the ability to simultaneously reshape and increase the buccolingual thickness of the supporting alveolar bone. A 24-year-old man with a Class I severely crowded malocclusion and an overly constricted maxilla with concomitant posterior crossbites and a 17-year-old female with a Class I moderately to sever...

Periodontitis is an immunoinflammatory disease that causes destruction of tooth supporting tissues. It is characterized by mulifactorial etiology involving bacterial biofilm and an inflammatory host response. The inflammatory ho destruction; thus novel therapeutic modalities should be considered that modulates host response. The proven efficacy of bisphosphonates to inhibit osteoclast bone reso...

OBJECTIVE The aim of the present study was to investigate the correlation between initial alveolar bone density of upper central incisors (ABD-UI) and external apical root resorption (EARR) after 12 months of orthodontic movement in cases without extraction. METHODS A total of 47 orthodontic patients 11 years old or older were submitted to periapical radiography of upper incisors prior to tre...

AIM Residual ridges change in shape and reduce in size due to alveolar bone resorption. Therefore, the purpose was to investigate changes in denture base thickness (DBT) and interocclusal rest space (IRS) with regard to the denture relining procedure. METHODS The IRS and DBT were measured (before and after denture relining) in the case of 74 patients and their removable dental prostheses by u...

It is extremely important to assess variations between the most used radiographs in dental practice, since minimum distortion on obtained images may change diagnosis, treatment plan, and prognosis for the patient. For this, the distance between the enamel-cementum junction and the alveolar bone crest was measured on conventional and digitized periapical, bitewing, and panoramic radiographs and ...

The retention of a complete denture and the patient’s adaptation varies considerably among different individuals. Resorption of the edentulous alveolar ridge differs greatly and some patients need implant-retained overdentures to enable adequate retention of their prostheses. In some extreme cases it is necessary to increase the volume of the alveolar ridge with bone grafts. The aim of this stu...

Skeletal mass is regulated by two key activities: bone removal (resorption) by hematopoietic lineage osteoclasts and bone matrix formation by mesenchymal lineage osteoblasts. During adult life, these activities occur sequentially on the same surface: a process termed as remodeling. Tiny packets of bone are removed by osteoclasts and replaced by new bone matrix produced by osteoblasts. This cont...
