Persistent hiccup can conceal life-threatening clinical conditions of highly heterogeneous nature... more Persistent hiccup can conceal life-threatening clinical conditions of highly heterogeneous nature. Here, we report a case of a persistent hiccup that has been temporally associated with dental implant insertion in a patient with paroxysmal atrial fibrillation. This 67-year-old patient underwent dental implant in area 36 and the procedure was performed without acute complications. A prolonged hiccup started ~48 h after the procedure: it failed to respond to several medications and it lasted for ~18 days, after which it spontaneously disappeared. Brain imaging and neurological examination were conducted in order to rule out organic conditions, even though all the investigations resulted to be negative. We suggest that the surgical procedure might have triggered a prolonged reflex activation. Knowledge about this complication of oral surgery procedure might be useful for avoiding unnecessary hospitalization or diagnostic tests.

Increased risk of maxillary sinusitis has been reported with the presence of periapical abscesses, periodontal disease, dental trauma, tooth extraction and implant placement when the sinusal membrane is perforated. MATERIALS AND METHODS A patient with odontogenic maxillary sinusitis associated with oro-nasal fistula was treated. RESULTS The follow-up at six months showed the complete resolution of maxillary sinusitis, palatal fistula got closed and pain symptoms disappeared. CONCLUSION This case report describes a rare complication of odontogenic maxillary sinusitis: the oro-nasal fistula.

Bone substitutes have received a wealth of reports in the literature demonstrating a long-term success when used in alveolar bone augmentation procedures. MATERIALS AND METHODS We reviewed articles comparing TiMesh GBR technique with different percentage of bone: autogenous bone alone (AB); anorganic bovine bone alone (ABB); 50:50 or 70:30. From an initial pool of 122, we selected 14 studies. ANOVA followed by Tukey HSD test was used for statistical analysis. RESULTS We present a table analysing fundamental parameters to value a successful GBR therapy. Autogenous bone remains the gold standard in GBR technique with TiMesh; however, the combination between AB/ABB in relation 50:50 and 70:30 allows reducing surgical cost exploiting properties of eterologous bone. CONCLUSION The use of autologous bone is associated with a height and width gain of bone, which...

The aim of this study is to describe an implant supported denture rehabilitation in an edentulous hemimandibulectomized patient with a singular prosthetic design in order to compensate for the lack of a condylar process. MATERIALS AND METHODS The subject of the clinical case, had a history of squamous cell carcinoma of the right tonsillar region for which it was subjected to a hemimandibulectomy and was primarily rehabilitated with an over denture mounted onto a bar furnished by a resin condylar eminence in articulation with the glenoid fossa of the upper denture. The need to provide greater stabilization for the upper prosthesis led to a maxillary implan...

Osteomas are benign osteogenic lesions considered as real tumours but without infiltrative or metastatic potential. Their growth potential is usually limited, but certain rare and large cases of peripheral osteoma are described in literature. Although surgery is recommended, there are no reports of malignant transformation. In this study, we describe successful implant rehabilitation in a patient with a central osteoma of the maxilla with immediate loading in a fresh extraction socket. MATERIALS AND METHODS The report concerns a 33-year-old woman with a compromised deciduous first molar in the left premolar region of the maxilla; an asymptomatic bony expansion of the palatal and vestibular sides of the left canine/premolar/molar area of the maxilla and by radiograph revealed a well-defined radiopaque mass. ...

Purpose: To analyze implant survival and autologous bone graft resorption after LSFE, in patients with at least 5 years follow-up. Materials and Methods: Thirty-three patients (mean age 56 years, range 46-68 years) who had undergone LSFE with intraoral autologous bone graft from mandibular ramus and simultaneous implant insertion were included. A minimum of 5 years of follow-up was required. The total peri-implant bone height was measured at mesial and distal aspects of the implants immediately after surgery (T0) and after a period ranging from 5 to 11.5 years after surgery (mean 7.65 AE 1.80 years) (T1) on digital panoramic and periapical radiographs. Wilcoxon matchedpairs signed rank test was used to compare bone graft height at T0 and T1. The influence of patient-, surgery-, and implant-related factors on the outcomes was investigated. Results: Of the 58 implants placed, no one was lost. All prostheses were in function, and no biological or mechanical complications occurred. The residual ridge height at the involved sites averaged 6.48 AE 1.72 mm. The mean bone height at grafted regions was 12.05 AE 2.47 mm at T0 and 12.13 AE 2.39 mm at T1 (not statistically significant). Marginal bone level change at T1 averaged −1.22 AE 1.60 mm. None of the evaluated factors significantly affected the results. Conclusion: Autologous bone grafts from intraoral donor sites display excellent volume stability over time that may contribute to optimal outcomes of the procedure.

The present study aims to clinically assess the regenerative ability of the ozone in the form of oil-based gel applied to the exposed bone area in the treatment of ORNJ. Materials and methods: Eight patients who underwent radiotherapy for the treatment of cervical or neck cancer were diagnosed with ORN of the jaws at our Department, for a total of 11 sites of necrotic bone exposure (3 patients were diagnosed with more than one site of osteoradionecrosis). In the therapeutic protocol, the exposed bone lesion and osteomucosal margin were cleaned with manual debridement. Then the ORN lesion was treated with topical applications of ozone delivered as oil suspension (Ozosan®-Sanipan, Clivio, Italy) on the exposed bone for 10 minutes. The application was repeated each week until movement of the necrotic fragment was noted Results: In six patients on 8 (75%) lesions resolved with complete mucosal healing with 3 to 19 ozone applications. Total sequestration of the necrotic bone with spontaneous expulsion was observed. One patient improved his conditions shifting from a stage B2S1 to B1S1 according to He et al. classification. A patient only worsened his conditions with treatment. No toxicity was reported or observed. Conclusion: These results showed the efficacy of ozone oil suspensions in the non-invasive treatment of ORN, probably related to its properties of stimulation of local revascularization and antibacterial activity, and the good tolerability of the related protocol used. Clinical significance: The use of this kind of medication should be included in ORNJ treatments as effective, noninvasive and self-administered.

Materials and methods: A total of 69 patients with 82 partially or completely formed SNT in the anterior maxillary region were identified over a 3-year period. All selected patients were assessed for the number, location, and family history of SNT, damage to adjacent roots, and associated symptoms. The surgical approaches used for removal were recorded. Postoperative clinical sequelae (loss of vitality, periodontal problems, pain, bleeding, and enanthema) were evaluated. Results: A total of 43, 30, and 9 SNT were extracted with palatal, buccal, and bicortical approaches respectively. Periodontal and vitality assessments revealed no problems in adjacent teeth at 6 months after surgery. Postoperative pain was within acceptable levels in all patients and subsided within 3 to 7 days. Mild postoperative bleeding occurred in eight patients. Enanthema subsided within 10 days in all patients. Conclusion: Our results suggest that early diagnosis and appropriate surgical treatment of SNT are important to decrease the risk of clinical complications.

In this article, we analyze different surgical techniques for tissue management during GBR and a modified partial-thickness surgical approach. In a year's time span, five patients were enrolled in the study: Four women and one man (aged 44-59 years). In four patients, a GBR with simultaneous implant placement was adopted, whereas in another patient, a delayed implant placement was done. The flap was of full thickness and overturned on the side palatal with the aim of a retractor, thus exposing the bone crest. The graft material was covered and protected with a resorbable collagen membrane (Geistlich Bio-Gide®, Switzerland). The periosteal layer of the flap was then positioned above the resorbable membrane without traction. The sutures as vertical mattress were then positioned. Each patient received an intramuscular betamethasone dose (4 mg/50 kg) and antibiotic...

We report a case of ORN of the posterior maxilla treated with Er: YAG laser and a pedicled buccal fat pad (bichat bulla adipose) flap. A 69-year-old man presented complaining of pain on left maxilla. He had received high-dose radiotherapy (90 Gy) for squamous cell carcinoma of the left soft palate 2 years earlier. Clinical and radiographic examinations revealed ORN of the left maxillary molar region and maxillary sinusitis. Daily home care consisted of 0.9% saline irrigation and 0.8% H2O2 gel application. Sequestrectomy and tooth extraction were followed by debridement with Er: YAG laser and repair with a pedicled buccal fat pad flap. Complete resolution of ORN and maxillary sinusitis was established one year postsurgically. The excellent clinical outcome suggests that Er: YAG laser debridement and pedicled buccal fat pad flap are a viable option to treat ORN of the posterior maxilla.

Materials and Methods: 32 patients receiving bisphosphonate were treated surgically. Patients were divided into three groups according to type of drug administrated and were subjected to a treatment of oral surgery, such as simple tooth extractions and extraction of all residual teeth of the oral cavity, upon evaluation of CTX values and antibiotic prophylaxis. Results: Within the sample of 32 patients, 12 patients had been treated with bisphosphonates for several years and none developed osteonecrosis of the jaw upon surgery. As for CTX, patients treated with oral bisphosphonates showed a mean value of serum Ctelopetides of 0.2869 ng/ml. The mean value of CTX did not differ significantly between patients taking oral bisphosphonates and healthy patients not treated with bisphosphonates. Conclusion: None of the patients subjected to preoperative antibiotic prophylaxis developed osteonecrosis of the jaw after surgery. The pharmacological and surgical protocol tested appeared valid in the prevention of osteonecrosis associated to bisphosphonates.
