AbstractSeveral authors have suggested that implants can be placed simultaneously with onlay bone grafts without affecting outcomes. Therefore, the purpose of this study was to answer the following clinical questions: (1) What are the outcomes of implants placed simultaneously with autogenous onlay bone grafts? And (2) is there a difference in outcomes between simultaneous vs delayed placement of implants with autogenous onlay bone grafts? Databases of PubMed, Embase, and Google Scholar were searched up to 15 November 2020. Data on implant survival was extracted from all the included studies (single arm and comparative) to calculate point estimates with 95% confidence intervals (CI) and pooled using the DerSimonian–Laird meta-analysis model. We also compared implant survival rates between the simultaneous and delayed placement of implants with data from comparative studies. Nineteen studies were included. Five of them compared simultaneous and delayed placement of implants. Dividing the studies based on follow-up duration, the pooled survival of implant placed simultaneously with onlay grafts after <2.5 years of follow-up was 93.1% (95% CI 82.6 to 97.4%) and after 2.5–5 years was 86% (95% CI 78.6 to 91.1%). Implant survival was found to be 85.8% (95% CI 79.6 to 90.3%) with iliac crest grafts and 95.7% (95% CI 83.9 to 93.0%) with intra-oral grafts. Our results indicated no statistically significant difference in implant survival between simultaneous and delayed placement (OR 0.43, 95% 0.07, 2.49, I2=59.04%). Data on implant success and bone loss were limited. Data indicates that implants placed simultaneously with autogenous onlay grafts have a survival rate of 93.1% and 86% after a follow-up of <2.5 years and 2.5–5years respectively. A limited number of studies indicate no significant difference in implant survival between the simultaneous and delayed placement of implants with onlay bone grafts. There is a need for randomized controlled trials comparing simultaneous and delayed implant placement to provide robust evidence.

Molar Extraction

The placement of immediate implants in the posterior sector is a widespread procedure where the success and survival rates are similar to those of traditional protocols. It has several anatomical challenges, such as the presence of interradicular bone septa that hinder a correct three-dimensional positioning of the implant and may compromise primary stability and/or cause damage of neighboring structures. The aim of this article is to present the treatment and the one-year clinical follow-up of a patient who received immediate implant placement using an interradicular bone-drilling technique before the molar extraction.

Introduction. This study aimed to report the characteristics and treatment outcome of 13 patients with solitary extramedullary plasmacytomas of the head and neck and analytical literature review. Materials and Methods. Nine patients (69%) were treated with gross surgical resection followed by radiotherapy, three (23%) were primarily treated with radiotherapy alone, and one (8%) was treated with surgery alone. Results. There were 3 women and 10 men with the median age of 52 years. Nasal cavity (46%) and paranasal sinuses (23%) were the most common primary sites. After a median follow-up of 28 months, 10 patients are alive and free of disease, one is alive with multiple myeloma, and two died of multiple myeloma. In the literature review the median age was 58 years and male/female ratio was 2.7. Sinonasal tract was the most common primary site. Ten-year local control and progression to multiple myeloma rates were 88% and 23%, respectively. The 5- and the 10-year overall survival rates were 71 and 69%, respectively. Conclusion. Radiation therapy with or without surgery is an effective treatment for patients with head and neck extramedullary plasmacytoma. However, long-term follow-up for detection of local recurrence and progression to multiple myeloma is essential.

Oral actinomycosis is not a common disease, but it can cause massive destruction. This article reports a case of implant failure associated with actinomycosis. A 55-year-old Caucasian male patient had tooth #20 extracted years ago and an implant placed 3 years ago. The #20 implant area developed an abscess about 1½ years after implant placement. Radiographic findings revealed a large radiolucency on the mesial aspect of the #20 implant. The implant was surgically removed and the lesion thoroughly debrided. The patient experienced severe pain when the apical soft tissue was curreted following implant removal. A periapical radiograph revealed that the lesion approached the mental foramen. A short course of antibiotics was prescribed. Histological observation found sulfur granules, which were found to be actinomycotic colonies. Peri-implant actinomycosis was diagnosed. No recurrence had occurred at the 1-year follow-up.

Abstract Objectives: This study evaluated the use of bone ring technique with xenogeneic bone grafts in treating horizontal alveolar bone defects. Material and methods: In total, 11 patients in need of horizontal bone augmentation treatment before implant placement were included in this retrospective study. All patients received simultaneous bone augmentation surgery and implant placement with xenogeneic bone ring grafts. We evaluated the postoperative efficacy of the bone ring technique with xenogeneic bone grafts using radiographical and clinical parameters. Results: Survival rates of implants were 100%. Cone-beam computed tomography revealed that the xenogeneic bone ring graft had significantly sufficient horizontal bone augmentation below the implant neck platform to 0 mm, 1mm, 2mm, and 3mm. It could also provide an excellent peri-implant tissue condition during the one-year follow-up after loading. Conclusion: The bone ring technique with xenogeneic bone ring graft could increase and maintain horizontal bone mass in the region of the implant neck platforms in serious horizontal bone defects.

Objetivo: Bio-Oss is a xenogene bone graft in which all organic components are removed while retaining their natural mineral architecture. Therefore, the aim of this study was to evaluate, through a literature review, the benefits of using Bio-Oss for tissue regenerative treatment prior to implant placement. Material and Methods: a search was performed in Pubmed (Medline) in order to identify articles published in English between January 1, 2000 and June 31, 2018, where the Bio-Oss graft was used prior to implantation of implants in humans. A total of 40 studies were selected for detailed analysis. From this analysis, 18 articles were identified for inclusion in this review. Results: the articles analyzed in the review showed several beneficial effects of this xenograft, such as: positive osteoconductive properties, recovery of bone heights at sites with severe atrophies, slow xenograft reabsorption suggesting long term stability, survival rates and success of implants placed in grafted sites ranging from 91 to 100% in several studies. Conclusion: the use of bio-oss as a bone substitute is a viable alternative in the placement before dental implants, being used in clinical practice and with proved efficacy in several studies, due to its similarity with the bone and its high level of osteoconductivity.KeywordsBio-Oss; Bone Graft; Implants.

There is no agreement of data in the subject of implant failure and the development of osteonecrosis in patients receiving antiresorptive agents. The purpose of this systematic review is to evaluate whether dental implants placed in patients on antiresorptive medication have an increased failure rate and whether the implant placement or the implant existence are risk factors for developing medication-related osteonecrosis of the jaw (MRONJ). An electronic search was conducted in PubMed/Medline and all publications fulfilling the inclusion criteria were included. The search was completed by a hand research of the references cited in all electronic identified publications and resulted in 411 articles. According to the inclusion criteria, 32 studies were included with a total of 5221 patients, 12 751 implants, 618 cases of implants loss and 136 cases of MRONJ analyzed. It cannot be established that antiresorptive medication affects the dental implant survival rates, because of small number of studies, most of them characterized by a low level of quality. The risk of MRONJ as an early or late complication is also not well established. Therefore, successful dental implant procedures on patients receiving antiresorptive medication might be possible, but more studies need to be carried out in the future to verify this topic. Apart from intravenous antiresorptive drugs, which remain an absolute contraindication, dental implantology in patients under antiresorptive medication is not a contraindication but it must be accompanied with a careful treatment planning, patients must be informed about the possible complications and large follow up periods are essential.

Background and Objectives: To integrate the available published data on patients with oral lichen planus (OLP) rehabilitated with dental implants, as well as to review the recommendations for OLP patients receiving implants. Materials and Methods: An electronic search was undertaken in February 2019 using five databases. Publications reporting cases of patients with OLP and rehabilitated with implant-supported oral prosthesis were included. Results: Twenty-two publications were included (230 patients, 615 implants). The overall implant failure rate was 13.9% (85/610). In patients with oral squamous cell carcinoma (OSCC) the failure rate was 90.6% (29/32), but none of these implants lost osseointegration; instead, the implants were removed together with the tumor. One study presented a very high implant failure rate, 76.4% (42/55), in patients with “active lichen planus”, with all implants failing between 7–16 weeks after implant placement, and its conflicting and incongruent results are discussed in detail. There was a statistically significant difference between the failure rates in implants installed in different jaws (maxilla/mandible) and when implants of different surfaces were used (turned/moderately rough), but not between patients with reticular or erosive OLP types, or between male and female patients. If OSCC patients and the cases of the latter study are not considered, then the failure rate becomes very low (2.7%, 14/523). The time between implant placement and failure was 25.4 ± 32.6 months (range 1–112). The mean ± SD follow-up was 58.9 ± 26.7 months (1–180). Conclusions: When the results of the one study with a very high failure rate and of the cases that developed OSCC are not considered, the dental implant failure rate in OLP patients was 2.7% after a follow-up of approximately five years. Recommendations are given when treating OLP patients with dental implants.

Large diaphragmatic defects present a reconstructive challenge, often necessitating the use of synthetic materials. We report our experience reconstructing large diaphragmatic defects using human acellular dermal matrix (HADM). Patients unable to undergo primary repair of diaphragmatic defects from 2009 to 2013 were reconstructed using HADM. A chart review was performed to investigate immediate and late post-operative outcomes. Construct stability was assessed with repeat imaging. In addition, a literature review was performed to identify studies in which HADM had been used for diaphragm repair. Four patients required reconstruction of large hemi-diaphragmatic defects. All patients had chest tubes placed, which remained in situ from 4 to 10 days post-operatively. Two patients also had drains in dead space surrounding HADM; these were removed between 6 and 9 days post-procedure. Length of hospital stay ranged from 8 to 65 days. Post-operative complications were seen in 2 patients: surgical site cellulitis and failure of extubation due to persistent respiratory failure. There were no adverse events related to HADM, and all patients remained disease free without evidence of repair failure on radiographic follow-up, ranging from 14 to 62 months. The literature review identified 3 studies in which all diaphragms repaired with HADM remained intact without need for explantation despite common post-operative complications including fluid collections and surgical site infections. Diaphragm reconstruction with HADM is limited to a small number of patients and modest follow-up periods; the neodiaphragms appear durable in contaminated fields, without evidence of repair failure. Our results, and previously published data, indicate HADM is a reasonable option for diaphragm repair.
