Compared to the currently clinically available bone grafting materials for alveolar ridge augmentation, there is a great demand for bioactive bone substitutes with higher resorbability, which enhance osteogenesis at the same time. This has prompted the development of a silicon-doped rapidly resorbable calcium alkali orthophosphate (Si-CAOP) and silicon-doped β-tricalcium phosphate (Si-TCP). This study evaluated the effect of these two particulate graft materials as compared to the currently clinically used β-TCP on bone formation and osteogenic marker expression after 2 weeks, 1, 3, 6, 12, and 18 months of implantation in critical size defects in the sheep scapula...

BACKGROUND: Advanced platelet-rich fibrin (A-PRF) is an autogenous blood product with applications in dento-alveolar surgery. However, there is minimal information regarding its optimal clinical application or efficacy. The aim of this multi-arm parallel randomized controlled clinical trial was to evaluate the efficacy of A-PRF alone or with freeze-dried bone allograft (FDBA) in improving vital bone formation and alveolar dimensional stability during ridge preservation. METHODS: Forty patients requiring extraction of non-molar teeth and replacement with dental implants were randomized into one of four ridge preservation approaches: A-PRF, A-PRF+FDBA, FDBA, or blood clot...

Purpose: An adequate bone volume for complete circumferential coverage of the implants is very important for obtaining a long-term success of oral implants. To avoid these problems various membranes and biomaterials were used, but soft tissue pressure could cause a membrane collapse toward the defect. The present work describes a ridge augmentation with titanium mesh shaped by adapting it to a bone defect in aesthetic areas. Materials and methods: Three patients with alveolar crest defects received three implants (Bone System, Milano, Italy) and the defects were filled with bone chips...

Alveolar bone is a mechanosensitive tissue that provides structural support for teeth. Alveolar bone loss is common with aging, menopause, tooth loss, and periodontitis and can lead to additional tooth loss, reduced denture fixation, and challenges in placing dental implants. The current studies suggest that sclerostin and DKK1, which are established osteocyte-derived inhibitors of bone formation, contribute to alveolar bone loss associated with estrogen ablation and edentulism in rats. Estrogen-deficient ovariectomized rats showed significant mandibular bone loss that was reversed by systemic administration of sclerostin antibody (SAB) alone and in combination with DKK1 antibody (DAB)...

BACKGROUND: After tooth loss, however, severely atrophic residual alveolar ridges are fairly common, especially in patients who have been edentulous for a long period. Anterior area of the mandible is areas where clinicians have greater anatomical limitations. Reduced alveolar bone height very often represents a contraindication to implant therapy, unless a procedure such as a ridge augmentation is performed. CASE REPORT: This study aims to present two separate cases in highly selected edentulous anterior mandibular sites, where one stage, mini implants were used to support total prostheses...

Sinus augmentation is a routine procedure performed in patients presenting with severe atrophy of the posterior maxillary alveolar ridge who seek dental implant surgery. Although this strategy is successful in large part, complications such as maxillary sinusitis, antral bleeding, resorption of graft material, infection, failure of implant installation, and oroantral fistula formation are documented on occasion. However, reports of postoperative maxillary cyst (POMC) arising after sinus augmentation are rare...

Alveolar ridge deficiency is considered a major limitation for successful implant placement, as well as for the long-term success rate, especially in the anterior maxillary region. Various approaches have been developed to increase bone volume. Among those approaches, inlay and onlay grafts, alveolar ridge distraction, and guided bone regeneration have been suggested. The use of titanium mesh is a reliable method for ridge augmentation. We describe a patient who presented with a localized, combined, horizontal and vertical ridge defect in the anterior maxilla...

Achieving excellence in anterior rehabilitations requires close cooperation between the periodontist and the prosthodontist. Many techniques can be used to restore the lost alveolar hard and soft tissues. The more severe the peri-implant defect, the higher the challenge and lower the predictability of the procedure. The present case consists of Seibert class III with mal-aligned implants in the esthetic zone resolved with a cost-modified treatment plan to re-establish esthetics in the anterior maxilla using rotated palatal flap...

Periodontal plastic surgery comprises an increasing part of clinical periodontology. Clinical trials have traditionally used professionals to judge esthetic outcome, and few studies have addressed patient needs and requests (true end points). Development of universally accepted and validated methods for professional esthetic assessment, together with standardized questionnaires for patient-perceived outcome, may help to provide better insights into the true needs and benefits of periodontal and implant-associated plastic surgery...

Loss of dentition leads to functional and esthetic challenges that are determined by the anatomic features of the edentulous area. These features can complicate the prosthetic rehabilitation of such patients, especially in situations where optimal esthetic outcomes are desired. For these reasons, reconstructive plastic surgery procedures, aimed at restoring the alveolar ridge to its former dimensions, have become of great clinical interest. These reconstructive plastic surgery procedures frequently involve soft-tissue augmentation, performed to improve the quality and quantity of mucogingival tissue with the aim to achieve an ideal esthetic result...

Diverse clinical advancements, together with some relevant technical innovations, have led to an increase in popularity of tunneling flap procedures in plastic periodontal and implant surgery in the recent past. This trend is further promoted by the fact that these techniques have lately been introduced to a considerably expanded range of indications. While originally described for the treatment of gingival recession-type defects, tunneling flap procedures may now be applied successfully in a variety of clinical situations in which augmentation of the soft tissues is indicated in the esthetic zone...

The reconstruction of deficient alveolar ridges using vertical and/or horizontal guided bone regeneration techniques allows for ideal implant placement, which is crucial for function and also for esthetically successful outcomes. Unlike in the past, when meeting a patient's functional demands was sufficient, many patients now have greater expectations from their implant restoration. Hence, it is no longer enough simply to restore the edentulous space with a functioning tooth or teeth. It has been suggested that patients now measure their final restoration using the contralateral natural tooth as the gold standard...

The rehabilitation of partially or totally edentulous patients with implant-supported prostheses has become routine, with excellent long-term outcome. A proper implant position is mandatory to achieve good functional and esthetic outcome and may require an adequate amount of alveolar bone and surrounding soft tissue. When this is lacking because of atrophy, sequelae of periodontal disease, traumas or congenital malformations, increased bone volume and/or keratinized mucosa can be obtained by guided bone regeneration, bone-grafting techniques and alveolar bone expansion...

It reports the results of primary basal blood flow in partially edentulous bone tissue with atrophy, as well as comparative evaluation of haemomicrocirculation level of the alveolar bone mucosa after bone augmentation via tunneling and conventional methods. The results of the initial state of microcirculation in the mucous membrane of the alveolar process in the partially edentulous area show a 45% decrease of blood flow (M), its intensity (s) by 60%. Microcirculatory shifts in blood flow levels indicators, its intensity, vasomotor activity are more evident when using the conventional method, where revascularization takes more than five months...

The objective of this study was to evaluate the effectiveness of precise three-dimensional hydroxyapatite printed micro- and macrochannel devices for alveolar ridge augmentation in a canine model. All grafts induced minimal inflammatory and fibrotic reactions. Examination of undecalcified sections revealed that both types of grafts demonstrated bone ingrowth. The majority of the bone growth into the block graft was into the channels, though a portion grew directly into the construct in the form of small bony spicules...

Aim of the study was to evaluate the reliability of 6 mm long implants compared to normal length implants placed in vertical augmented atrophic posterior mandible, supporting cemented single crowns. Thirty-six patients with bilateral posterior edentulous mandible and presented a bone availability height less than 9 mm from the mandibular canal were enrolled for the participation to this study. Patient hemi-arches were randomized to receive both 6 mm-long and normal length implants (10 mm). The technique used for the vertical bone augmentation was the "sandwich" technique, using a bone substitute block as graft...
