Efficacy of Alveolar Ridge Preservation after Maxillary Molar Extraction in Reducing Crestal Bone Resorption and Sinus Pneumatization: A Multicenter Prospective Case-Control Study.

AIM: To evaluate, with three-dimensional analysis, the effectiveness of alveolar ridge preservation (ARP) after maxillary molar extraction in reducing alveolar bone resorption and maxillary sinus pneumatization when compared to unassisted socket healing. METHODS: Patients were included in the study following inclusion criteria and underwent minimally traumatic maxillary molar extraction followed by ARP using synthetic nanohydroxyapatite (Fisiograft Bone, Ghimas, Italy) (test group) or unassisted socket healing (control group). Cone-beam computerized tomographies (CBCT) were performed immediat

A new approach for better anterior esthetic using platelet-rich fibrin as sole graft material combined with ovate design dental bridge.

Alveolar ridge deficiency is considered a major esthetic limitation, especially in the maxillary anterior region. Several approaches have been developed to enhance and increase the soft-tissue volume. Among those approaches are connective tissue grafts, platelet-rich fibrin (PRF) membrane and implying the guided bone regeneration concept. The PRF grafting technique was employed in this clinical case to improve and enhance the anterior esthetic without the need for the bone graft and augmentation. This article describes the use of PRF as a sole grafting material for both socket and soft-tissue

Tapered, Double-Lead Threads Single Implants Placed in Fresh Extraction Sockets and Healed Sites of the Posterior Jaws: A Multicenter Randomized Controlled Trial with 1 to 3 Years of Follow-Up.

PURPOSE: To evaluate the survival, success, and complication rates of tapered double-lead threads single implants, placed in fresh extraction sockets and healed sites of the posterior jaws. METHODS: The enrolled patients were randomly divided into 2 groups: in the test group (TG), all implants were inserted at the time of tooth extraction; in the control group (CG), all implants were placed 3 months after extraction. The implants were followed for a period of 1 to 3 years after loading. The main outcomes were implant survival, complications, and implant-crown success. RESULTS: Ninety-two pat

A digital evaluation of alveolar ridge preservation at implants placed immediately into extraction sockets: an experimental study in the dog.

OBJECTIVE: To compare with pristine sites bone resorption and soft tissue adaptation at implants placed immediately into extraction sockets (IPIES) in conjunction with deproteinized bovine bone mineral (DBBM) particles and a collagen membrane. MATERIAL AND METHODS: The mesial root of the third premolar in the left side of the mandible was endodontically treated (Test). Flaps were elevated, the tooth hemi-sectioned, and the distal root removed to allow the immediate installation of an implant into the extraction socket in a lingual position. DBBM particles were placed into the defect and on th

Magnesium-enriched hydroxyapatite at immediate implants: a histomorphometric study in dogs.

AIM: To evaluate the influence of magnesium-enriched hydroxyapatite (MHA) (SintLife(®)) on bone contour preservation and osseointegration at implants placed immediately into extraction sockets. MATERIAL AND METHODS: In the mandibular pre-molar region, implants were installed immediately into extraction sockets of six Labrador dogs. MHA was placed at test sites, while the control sites did not receive augmentation materials. Implants were intended to heal in a submerged mode. After 4 months of healing, the animals were sacrificed, and ground sections were obtained for histomorphometric evaluat

Improving the Prognosis of Periodontally Involved Teeth at the Time of Extraction of Adjacent Teeth With an Amnion-Chorion Barrier and Bioactive Dentin Graft.

With increased awareness, both in the dental literature and by the general public, of peri-implant disease, a growing trend in dentistry is to save teeth with a "questionable" periodontal prognosis. This prospective study involving such patients was designed to evaluate the effects of combining a bioactive barrier and graft, not on the socket but to augment adjacent periodontal conditions on teeth with severe periodontal bone loss at the time of extraction of an adjacent tooth. Fifteen patients were selected; teeth were extracted, ground, prepared with a pH 11 cleanser, partially demineralized

An osteopenic/osteoporotic phenotype delays alveolar bone repair.

Aging is associated with a function decline in tissue homeostasis and tissue repair. Aging is also associated with an increased incidence in osteopenia and osteoporosis, but whether these low bone mass diseases are a risk factor for delayed bone healing still remains controversial. Addressing this question is of direct clinical relevance for dental patients, since most implants are performed in older patients who are at risk of developing low bone mass conditions. The objective of this study was to assess how an osteopenic/osteoporotic phenotype affected the rate of new alveolar bone formation

Clinical and laboratory markers in predicting the probability of alveolitis occurrence.

OBJECTIVE: Aim: Our aim was to identify the markers necessary to predict the probability of alveolitis in case of tooth extraction under the conditions of a clinical laboratory and within the workplace of a dental surgeon. PATIENTS AND METHODS: Materials and Methods: 160 patients were under our supervision. Since men and women may undergo tooth extractions throughout their lives, we selected adult patients (from 18 to 75 years old) including 100 men and 60 women. The effectiveness of classical methods was studied and compared according to the treatment protocol and drug treatment regimens dev

Factors affecting incidence of dry socket: a prospective community-based study.

Dry socket, or alveolar osteitis, can occur because of the removal of teeth. No clear etiology has been acknowledged; however, numerous risk factors have been proposed and tested. We report on the results of a prospective, multicenter study of the incidence and factors affecting the occurrence of alveolar osteitis at the Royal Dental Hospital of Melbourne and Community Dental Clinics in Melbourne, Australia. Ethics approval was gained from the University of Melbourne and Dental Health Services Victoria. The data were analyzed in a descriptive fashion, and the factors affecting alveolar osteiti

The teeth were extracted using a 3D-printed titanium surgical guide in the experimental group; free-hand extractions were performed in the control group. The surgical duration, tooth sectioning duration, cortical bone perforation, and postoperative complications, including pain

Buccal and lingual bone level alterations after immediate implantation of four implant surfaces: a study in dogs.

OBJECTIVES: Bone formation and maintenance around implants placed immediately after tooth extraction may be affected by implant surface treatment and compromise long-term esthetic results. This study morphometrically evaluated buccal bone loss and bone-to-implant contact (BIC) of four implant systems placed immediately after tooth extraction in a dog model. MATERIAL AND METHODS: The premolars of eight beagle dogs were bilaterally extracted with a full-thickness flap, and root-form dental implants were placed on the root extraction socket. Implants (n = 16 each) with different surface treatmen

Immediate single tooth replacement with subepithelial connective tissue graft using platform switching implants: a case series.

This case series evaluated the facial gingival stability following single immediate tooth replacement in conjunction with subepithelial connective tissue graft (SCTG). Implant success rate and peri-implant tissue response were also reported. Ten patients (6 male, 4 female), with a mean age of 52.1 (range = 22.7 to 67.1) years, underwent immediate implant placement and provisionalization with SCTG and were evaluated clinically and radiographically at presurgery (T0), at the time of immediate tooth replacement and SCTG (T1), and 3 months (T2), 6 months (T3), and 12 months (T4) after surgery. Dat

Restorative artificial intelligence-driven implant dentistry for immediate implant placement with an interim crown: A clinical report.

Immediate implant placement into the extraction socket based on a restoratively driven approach poses challenges which might compromise the delivery of an immediate interim restoration on the day of surgery. The fabricated digital design of the interim restoration may require modification before delivery and may not maintain the planned form to support the gingival architecture for the future prosthetic volume for the emergence profile. This report demonstrates how to utilize the artificial intelligence (AI)-assisted segmentation of bone and tooth to enhance restoratively driven planning for i

Effect of Bacterial Nanocellulose with Chemisorbed Antiseptics on Alveolar Bone Repair in Rats Undergoing Bisphosphonate Therapy.

Objectives: This work investigated the effect of bacterial nanocellulose (BNC) alone or with chemisorbed chlorhexidine or povidone-iodine on post-tooth extraction repair in rats undergoing bisphosphonate therapy. Methods: Forty Wistar rats were treated with zoledronic acid, subjected to tooth extractions and allocated into groups according to the material inserted in the post-extraction socket: (1) BNC (n = 10); (2) BNC/Iodine (n = 10); (3) BNC/Chlorhex (n = 10); (4) Control (n = 10). Maxillae were dissected and macro- and microscopically analyzed. Results: Oral lesion frequency on macroscopic

Replantation After Dental Avulsion: A Scoping Review and Proposal of a Flow Chart.

Dental avulsion, the complete displacement of a tooth from its socket, is a severe dental trauma with a prevalence of 0.5% to 16% of all dental injuries. Replantation of avulsed teeth is common, yet recent studies show high failure rates and unpredictable long-term outcomes. This review examines clinical variables influencing intentional dental replantation decisions and proposes a treatment flow chart. A comprehensive literature search was conducted in PubMed-Medline, Scopus, WoS, and Cochrane databases using the keywords "tooth avulsion," "tooth replantation," and "tooth ankylosis." Inclusio

Autotransplantation of retained canines unable to undergo orthodontic traction. A clinical report.

AIM: The canine is the tooth that, together with the third molar, presents the highest risk of inclusion: 85% of these teeth are located in the palate and 15% in the buccal area. In most treatment plans, retained canines are driven to extrusion through orthodontic treatment. However, in some cases, for technical reasons or patient choice, it is not possible to perform this consolidated approach. The present clinical report evaluates 10 ectopic canines transplanted in both adults and younger patients with up to 60 months of follow-up. CASE DESCRIPTION: Two clinical cases are described in detai
