Stomatognathic System

Dental implants and alternatives for patients requiring restoration of stomatognathic system through the replacement of dental units are an increasingly common practice. Treatment of patients with additional complications to dental implant restorations is a constant challenge, especially the patients described in the literature about the failure involving the use of bisphosphonates based drugs, those being touted as directly responsible for the presence of a pathological condition called bisphosphonate-related osteonecrosis of the jaw. A search through two databases was conducted to clarify doubts about the actual influence of factors presented and its true relevance to clinical practice, promoting the knowledge and more consistent strategies in cases requiring rehabilitation intervention. The results show the need for additional research on these topics.

Implant Treatment

Dental implant treatment is a highly predictable therapy, but when potentially lethal symptoms or complications occur, dentists must remove the implant fixture. Recently, reports on antiresorptive agent-related osteonecrosis of the jaw have increased in the field of dental implants, although the relationship between dental implant treatment and antiresorptive agents remains unclear. Here, we report a case of antiresorptive agent-related osteonecrosis of the jaw that developed after dental implant removal. A 67-year-old Japanese woman with a medical history of osteoporosis and 7 years of oral bisphosphonate treatment was referred to our hospital with a chief complaint of painful right mandibular bone exposure. A family dentist removed the dental implants from the right mandible using a trephine drill without flap elevation in August 2016. However, the healing was impaired; she was referred to our hospital 3 months after the procedure. We performed a sequestrectomy of the mandible under general anesthesia. In conclusion, this patient's course has two important implications: First, the removal of dental implants from patients who are prescribed oral bisphosphonates for long durations can cause antiresorptive agent-related osteonecrosis of the jaw. Second, meticulous procedures are required to prevent and treat the development of antiresorptive agent-related osteonecrosis of the jaw after dental implant removal.

Oral bisphosphonates are commonly used to improve bone density in patients who suffer from a variety of pathologies. However, they have also been known to cause bisphosphonate-related osteonecrosis of the jaws (BRONJ). The aim of this clinical case presentation is to (1) determine whether the currently recommended length of time that oral bisphosphonates should be discontinued, before performing dental implant surgery, is sufficient to prevent BRONJ and (2) to describe an alternative treatment for BRONJ. A 65-year-old female patient developed BRONJ after receiving mandibular dental implants 5 months after discontinuing alendronic acid (Fosamax). The BRONJ was treated by surgical osteotomy and plasma rich in growth factors (PRGF), and the patient was followed up with biweekly examinations, which included 0.2% chlorhexidine mouthwashes and removal of any remaining necrotic bone. The dental implants were loaded 41 weeks after surgery and followed up with periapical radiographs and implant stability quotient measurements at 3, 6, 12, and 24 months postloading. Although the Association of Oral and Maxillofacial Surgeons protocols for suspension of presurgical oral bisphosphonates were followed, this patient still developed BRONJ after implant surgery. While a multitude of treatments have been described in the literature, there is not enough scientific evidence to support any one treatment. Based on this clinical case, it can be concluded that the potential adverse effects of oral bisphosphonates on the jaws could be greater than expected and that treatment with PRGF produces promising results, although more long-term studies are necessary to confirm these findings.

The accidental migration (i.e., displacement) of dental implants into the maxillary sinus is a relatively common complication in dental clinical practice. Here, we report the extremely rare nasal cavity migration of a dental implant in a 23-year-old man. Considering the superficial location of the dental implant and the absence of oronasal fistula formation, we attempted to remove the implant via endoscopy, nasal bayonet forceps, curved hooks, and suction in an ambulatory surgery setting with the patient under local anesthesia. Importantly, we were able to extract the implant with only minor complications. The patient received medication for 2 weeks and exhibited uneventful healing. Our findings may be useful for physicians and dentists who encounter similar situations in clinical practice.

Цель исследования состояла в разработке неинвазивного метода диагностики состояния тканей периимплантационной зоны после постановки дентальных имплантатов, а также прогноза течения послеоперационного периода и ранней диагностики послеоперационных осложнений, таких, как мукозит и периимплантит, при одноэтапном методе дентальной имплантации. Методы. В исследовании представлена цитологическая характеристика отпечатков из области контакта имплантата с десной, в которых оценивали состояние эпителиальных клеток при различных проявлениях цитопатологии. Определяли индекс деструкции (ИД) и воспалительно-деструктивный индекс (ВДИ) в клетках воспалительного инфильтрата, которые сопоставляли с клинической картиной течения послеоперационного периода. Сроки забора цитологического материала 1, 5, 15, 25, 30, 60, 120 дней после постановки имплантатов. Количество исследованных цитограмм - 442 от 11 пациентов (по 1-2 имплантата). Общий массив использованных для вычисления интегральных показателей составил »2550. Результаты. Было установлено, что в сроки 1-5 дней после постановки дентальных имплантатов происходит резкое повышение показателей ИД (до 7500 ± 15) и ВДИ (до 80 ± 20), что отражает процесс развития в области имплантатов острых воспалительных реакций. В отдаленные сроки наблюдений отмечалось 2 варианта развития событий. Первый из них характеризовался сохранением во все сроки высоких показателей ИД и ВДИ. Для второго варианта динамики показателей было характерно их падение, что соответствовало развитию процесса остеоинтеграции дентальных имплантатов. The objectives of the investigation were to develop protocols evaluating the validity and effectiveness of the cytological method for diagnosis and prognosis of tissue conditions adjacent to a dental implant. Methods. This study examined the cytological characteristics of imprints of the gingiva-implant contact area, a. the correlation of quantitative ratios of epithelial cells either with or without hystopathological manifestations (an index of destruction, ID); b. ratio of cells of the inflammatory infiltrate (an inflammatory and destructive index, IDI); these data were researched in relation with dynamics of the clinical pictures during a postoperative period.The cytological material was obtained 1, 5, 15, 25, 30, 60, 120 days after dental implantation. Totally 442 cytogramme from 11 patients (1-2 implant per a patient) were assayed. The data array for computation of integrated indicators was composed of ca. 2550 data points. Results. A significant increase of ID (7500 ± 15) and IDI (80 ± 20) indicators, which reflects the development of acute inflammatory reactions in tissues neighboring an implant, was observed within 1-5 days following the insertion of dental implants. Long-term observations revealed two scenarios. The first scenario was characterized by the retention of high levels of ID and IDI over the period of observations. The second scenario featured the reduction of ID and IDI indices, which corresponded to the development of the osseointegration of dental implants.

1. Background: Loss of permanent teeth is very common, affected chewing function, speech and aesthetics; restoration of missing teeth with dental implant has several advantages, but we need thoroughly study the clinical and X ray features at the position at missing teeth, then to select the type of implant and make the best plan for the dental implant patients. 2. Materials and method: Cross-section descriptive study. From January 2009 to November 2010, study with 56 patients with 102 implants of MIS and Megagen systems at the Faculty of Odonto-Stomatology, Hue College of Medicine and Pharmacy and Vietnam-Cuba Hospital in Ha Noi. 3. Results: Distributed equally in male and female, common ages 40 – 59 (55,4%), the majority of missing teeth occurs in the lower jaw (63,8%) and especially, the teeth 36 and 46 (25,4%). The majority of missing teeth due to dental caries, dental pulp and apical diseases (64,7%) of the molar teeth (51,9%); the most position of missing tooth have enough bone for dental implants (87,3%), time of tooth loss and bone status in the position of tooth loss are related to each other (p < 0,01). Diameter and length of implant usually used 4.0 – 6.0 mm (63,7%) and 8.5 – 13.0 mm (83,3%). 4. Conclusion: Clinical and X ray features of edentulous patients has an important role in determining the type of implants and treatment planning of dental implants. Key words: Loss of permanent teeth, X ray and clinical features, Dental implant.

Abstract Background The purpose of this study was to analyze medium-to-long-term implant success and survival rates, and lower lip sensory disturbance after placement of dental implants with simultaneous inferior alveolar nerve (IAN) repositioning. Methods Fifteen patients (3 men, 12 women) treated in two centers were included in this retrospective study. The ages of the participants ranged from 19 to 68. A total of 48 dental implants were placed in 23 posterior mandibular segments simultaneously with IAN transposition or lateralization. The residual bone above the IAN ranged from 0.5 to 7.0 mm. Crestal bone changes were measured using cone beam computed tomography (CBCT) images. Disturbance of the IAN was evaluated subjectively using a modified questionnaire. Results The healing process was uneventful in fourteen patients. In one patient, spontaneous fracture of the operated mandible occurred on tenth day after the surgery. The implant in the fracture line was removed at the time of open reduction and fixation. One more implant was lost after 5 years of loading. Therefore, the overall dental implant survival rate was 95.8%, whereas all implants in function were judged as successful after a follow-up period of 1 to 10 years. Transient neurosensory disturbances (ND) were observed in all patients who underwent IAN lateralization and IAN transposition. At follow-up times of 3 years, 5 years, and 10 years, weak hypoesthesia remained in two subjects treated with IAN transposition. None of the patients developed neuropathic pain after the procedure. Conclusions Within the limitations of this study, we conclude that reconstruction of severely resorbed mandibles with dental implants in conjunction with IAN repositioning is an effective and reliable technique. Although neurosensory disturbances are the most common complication after surgery, they tend to resolve over time. Advanced surgical skills are required to perform this technique.

Background/Aim. Flapless implant surgery has become very important issue during recent years, mostly thanks to computerization of dentistry and software planning of dental implants placements. The aim of this study was to compare flap and flapless surgical techniques for implant placement through radiographic and radiofrequency analyses. Methods. The experiment was made in five domestic pigs. Nine weeks following domestic pigs teeth extraction, implants were placed, on the right side using surgical technique flap, and flapless on the left side. Digital dental Xrays were applied to determine primary dental implant stability quality (ISQ). At certain intervals, not later than three months, the experimental animals were sacrificed, and just before it, control X-rays were applied to measure dental implants stability. Results. Radiographic analysis showed that peri-implant bone resorption in the first 4 weeks following placement implants with flap and flapless surgical techniques was negligible. After the 3 months, mean value of peri-implant bone resorption of the implants placed using flap technique was 1.86 mm, and of those placed using flapless technique was 1.13 mm. In relation to the primary dental implant stability in the first and second week there was an expected decrease in ISQ values, but it was less expressed in the dental implants placed using the flapless technique. In the third week the ISQ values were increased in the dental implants placed by using both techniques, but the increase in flapless implant placement was higher (7.4 ISQ) than in flap implant placement (1.5 ISQ). The upward trend continued in a 4- week period, and after 3 months the dental implant stability values in the implants placed using flap technique were higher than the primary stability for 7.1 ISQ, and in the implants placed using flapless technique were higher comparing to the primary stability for 10.1 ISQ units. Conclusion. Based on the results of radiographic and resonance frequency analyses it can be concluded that the flapless technique in surgical implants placemat, leads to better results.

Dental implants are becoming increasingly used in current dental practice. This increased demand has motivated manufacturers to develop varieties of product through design, but also looking for new materials used to improve surface characteristics in order to obtain a better osseointegration. But the increase in the use of implants goes to a consequent increase in the number of failures. These failures are caused either by treatment complications (peri-implantitis), by fatigue breakage under mechanical over-stress, by defective raw material, or due to errors during the insertion procedures. Although they are rare, these complications are serious in dentistry. Before to market a dental implant to clinical practitioners, the product is validated among other determinations in number of biocompatibility research. Raw material issues, details about its structure and properties are less published by the scientific literature, but all this are subject of a carefully analysis of the producers. Breaking of dental implants during surgical procedures, during the prosthetic procedures or during use (chewing, bruxism, accidents, etc.), is the second most common cause of loss of an implant after consecutive peri-implantitis rejection. Although the frequency of this type of failure for a dental implant is much smaller than those caused by the peri-implantitis, a detailed study of broken implants can explain possible causes. The use of scanning electron microscopy (SEM) in the study of the cleave areas explain the production mechanism of cleavages, starting from micro-fissures in the alloy used for the production of dental implants. These micro-fissures in weak areas of the implant (anti-rotational corners of the polygons, etc.) could generate a serious risk of cleavage first time when a higher force is applied.

This study was designed to evaluate the accuracy of a novel computer-designed and selectively laser sintered surgical guide for flapless dental implant placement in the edentulous jaw. Fifty dental implants were placed in 11 patients with at least one totally edentulous jaw. Initially, cone-beam computed tomography (CBCT) was performed in each patient to define the virtual position of the dental implants based on the assessment of bone availability and the proposed dental prosthesis. After virtual planning, 3D surgical guides were printed using selective laser sintering. CBCT was repeated after the surgery, and the pre-and postoperative images were overlapped in the CAD software to compare the planned and actual positions of the dental implants using a one-sample t-test. The mean ± angular standard deviation between the long axes of the planned and final dental implant positions was 4.58 ±2.85 degrees; The linear deviation in the coronal position was  0.87 ± 0.49 mm and  in the apical region of the dental implants was 1.37 ± 0.69 mm. These differences were statistically significant (p &lt;0.001). The proposed modifications reduced the deviations, resulting in an improvement in the technique. We were able to place implants and temporary prostheses using the present protocol, taking into account the differences between the planned and final positions of the dental implants.
