The marginal bone resorption at the implants was 1.68 mm (SD = 0.44) after 1 year and 1.85 mm (SD = 0.98) after 4 years. The cumulative success rate based on defined criteria was 96% in the first year but decreased to 40% at 4 years because of marginal bone loss. The Kaplan–Meier algorithm demonstrated a better outcome for female patients, removable dentures, and total edentulism. No differences were detected among diameters, lengths, and implant site. Implants placed in FFAB showed a high SVR similar to that reported in previous studies on maxillae grafted with autogenous iliac crest bone. Although our data point to more marginal bone loss in partially edentulous patients and for fixed prosthetic restorations, the use of FFAB for reconstruction of the atrophic jaw prior to implant placement can be considered as a reliable alternative to autogenous bone.

Abstract
Gingival recessions are usually treated with surgical therapies which involve the use of connective tissue autograft in order to thicken the gingival tissue. This has an important biological repercussion on patients since they will have surgical wounds in two different oral cavity sites. In this case report, we offer an alternative technique for the treatment of a Miller class I gingival recession. A 40-year-old female patient has been treated with a combination of bilaminar and coronally advance flap techniques to cover a Miller class I gingival recession with addition of cryopreserved human amniotic membrane. The human amniotic membrane has been employed to thicken the keratinized tissue. The human amniotic membrane in combination with bilaminar and coronally advance flap techniques has produced aesthetically and functionally satisfying results, covering completely the gingival recession and restoring the natural colour and thickness of the gingiva. Bilaminar technique with coronally advanced flap and cryopreserved human amniotic membrane is a valid alternative in treating Miller class I and II gingival recessions and reduce the biological morbidity of a double intervention.
Clinical similarities and histological diversity comparing fresh frozen onlay bone blocks allografts and autografts in human maxillary reconstruction
Clinical similarities and histological diversity comparing fresh frozen onlay bone blocks allografts and autografts in human maxillary reconstruction

In the absence of autologous bone for harvesting, fresh-frozen bone allografts turned into an alternative for bone reconstruction procedures. The purpose of this study was to make a histological analysis of fresh-frozen onlay bone allografts (ALs), compared with autografts, in patients who needed maxillary reconstruction prior to dental implants placement. Twelve patients with bone deficiencies (width inferior to 4 mm) in the sites where the implants were planned were enrolled in the study. From these, six were elected to be treated with autogenous (AT) bone grafts and six with fresh-frozen bone AL. This last group included the patients who had absence of a convenient amount of bone in donor sites. Each patient received from one to six graft blocks, totalling to 12 ATs and 17 ALs. Seven months after grafting procedures, biopsies of the grafts were made using 2-mm internal diameter trephine burs, and processed for histological analysis. One biopsy was retrieved from each patient. Clinically, all grafts were found to be firm in consistency and well-incorporated to the receptor bed. Histological analysis showed a large amount of necrotic bone surrounded by few spots of new-formed bone in the AL group, suggesting low rate of graft remodeling. In the AT group, an advanced stage of bone remodeling was seen.
Human fresh-frozen bone block AL showed clinical compatibility for grafting procedures, although associated to slow remodeling process. Further studies are needed to define, at long term, the remodeling process chronology the clinical longitudinal results for fresh-frozen bone

Demineralized freeze-dried bone allograft (DFDBA) has been used extensively in periodontal therapy. Questions have been raised however, about the osteogenic potential of the variety of grafts available. In India the cost factor is another important consideration. The aim of this study therefore was to evaluate the clinical efficiency of the low priced, indigenously prepared DFDBA obtained from the Tata Memorial Hospital (TMH) Tissue Bank, in periodontal regeneration in infrabony periodontal defects, as compared to DFDBA obtained from the Pacific Coast Tissue Bank (DEMBONE). The latter was used as the control. 16 patients with bilaterally similar periodontal infrabony defects were selected, and randomly allotted to the test and control groups.

Abstract
Approaches providing the positioning of human amniotic membrane (HAM) within the intra-articular
space of arthritic TMJs have never been investigated. This contrasts with the increasing amount of evidence
suggesting the potential positive effects of HAM on a number of surgical conditions, even included
the interpositional arthroplasty for TMJ ankylosis. Thus, the possible usefulness of HAM to restore joint
functions in severely damaged TMJs could be hypothesized.
Based on these premises, the clinical research question ‘‘Is human amniotic membrane positioning
effective to reduce symptoms and restore jaw function in patients with severe inflammatorydegenerative
disorders of the temporomandibular joint?" has been addressed by performing a systematic
review of the literature. Out of potential 11988 and 8883 citations in the PubMed and Scopus databases,
respectively, only five were of possible interest for inclusion in the review, but none of them addressed
specifically the clinical research question.
Thus, the hypothetical background for usefulness was discussed. The benefits of HAM positioning in
TMJs with severe inflammatory-degenerative disorders could be related with its anti-inflammatory
and anti-microbial and analgesic properties as well as its low immunogenicity. Studies in which HAM
is positioned within the joint space of patients with severe TMJ degeneration, either as a discreplacing
film during major surgeries for discectomy and arthroplasty or as an injectable solution that
can be needle-inserted after an arthrocentesis procedure, should be designed to test the hypothesis.

Abstract
Mucogingival surgery has the objective to obtain coverage of the recession, with a favorable long-term prognosis, but also to minimize postoperative problems and surgery-related risks. Human amniotic membrane is increasingly employed for periodontal tissue repair in order to promote epithelialization and to reduce pain and scar tissue formation. A 38-year-old female patient reports dental hypersensitivity resulting from gingival recession affecting tooth 4.1. A mucogingival surgical procedure was proposed and a partial-thickness flap of epithelial-connective tissue was harvested from the palate and grafted on to the receiving site. The amniotic membrane was positioned at the donor site to reduce postoperative morbidity and to encourage rapid palatal healing. One week after the application of HAM (human amniotic membrane), the wound was healed and 1 month after the donor site was completely re-epithelialized. The present case report suggests that in the surgical treatment of gingival recession with palatal epithelial-connective tissue graft, HAM promotes rapid epithelialization of the palatal donor site wound with a reduction in morbidity.

Abstract
The aim of this study was to evaluate the clinical outcome of the surgical repair of oral mucosal defects using cryopreserved human amniotic membrane (HAM) as a graft material. Thirty-four patients with precancerous lesions such as leukoplakia, erythroplakia, and verrucous hyperplasia were included. Fresh amniotic membrane was obtained from women undergoing elective caesarean section; the membrane was cleaned, prepared in antibiotic solutions, and preserved at -80 °C. Results suggested that HAM promotes healing and epithelialization without specific complications. Thus we conclude that the use of HAM gives promising results in the repair of post-surgical oral mucosal defects.
