Patients with tooth loss in the posterior mandible,requiring dental implantation, mayalso require other simultaneous surgical procedures due to severe atrophy, such as nerve lateralization. However, it is difficult to achieve the appropriate width and height in this area in patients with atrophic ridges. In the present case, we performed inferior alveolar nerve (IAN) repositioning and iliac bone grafting simultaneously to achieve satisfactory width and height in an edentulous adult patientwith insufficient bone height and width in the posterior mandible. The follow-up did not indicateany nerve damage, anda significant increase was observed in the bone height, which facilitated successful implantation. This study showed the feasibility of IAN repositioning withsimultaneous iliac bone autogenous grafting for thetreatment of atrophic posterior mandibular ridges. However, further studies are required to confirm the safety and efficacy of this combinational method.

Purpose Despite the early diagnosis and treatment of developmental dysplasia of the hip (DDH), some older children still need open reduction. It is usually difficult to get a satisfactory reduction particularly in patients with acetabular defect. The purpose of this study was to evaluate the short-term outcomes of acetabulum reaming and sartorius muscle pedicle iliac bone grafting in the treatment of older children with DDH and acetabular defect. Methods The records of 15 patients with DDH (mean age 113.9 months (sd 29); 17 hips) who were treated with the reported technique between February 2015 and January 2017 were retrospectively reviewed. All patients acquired regular clinical and radiographic follow-ups, and alterations in the acetabular index, centre-edge angle and acetabular head index were measured. Joint function and radiographic results were evaluated with McKay and Severin modified criteria, respectively. Results A total of 15 patients were followed up for mean 32.4 months (sd 6.9). The percentages of excellent and good conditions were 94.1% (16/17) according to the Severin modified criteria and 88.2% (15/17) according to the McKay modified criteria. Avascular necrosis of the femoral head and redislocation only occurred in one hip. No cases of ankylosis or bone graft absorption occurred during the follow-up. Conclusion Reaming the acetabulum and sartorius muscle pedicle iliac bone grafting for repairing the acetabular defect can recover the arcuate structure by increasing the volume of the acetabulum, which is beneficial for achieving a concentric reduction. The short-term outcome was satisfactory, while the long-term results need to be further observed. Level of Evidence IV – retrospective study

Background. Atrophy of the posterior maxilla as a consequence of tooth loss and sinus pneumatization is a frequent condition encountered in the clinical practice. Prosthetic rehabilitation with implants in these patients often requires some kind of bone regeneration procedure to increase the bone volume. Aim. The aim of the present retrospective study is to analyze the survival and success rates of a series of implants placed in the atrophic posterior maxilla with a transcrestal osteotome procedure, without placing a bone grafting material. Materials and Methods. From 2006 to 2014, 36 dental implants (Neoss Ltd., Harrogate, UK) were inserted in 36 patients with at least 4 mm of bone below the maxillary sinus using transcrestal osteotome sinus floor elevation and placement of collagen sponge below the sinus membrane. ISQ measurements were made after implant placement and at abutment surgery after 4 to 6 months. The vertical bone height (VBH) was evaluated in intraoral radiographs taken prior to surgery and in radiographs from annual check-up appointments 5 to 13 years after implant placement. In addition, marginal bone loss (MBL) was evaluated. Results. One implant was lost after four years of prosthetic loading. The remaining 35 implants showed no complications and were loaded with single crowns after 4–6 months of healing. All 35 implants showed clinical success after 8.5 ± 2.8 years of prosthetic loading (from 5 to 13 years). The vertical bone height was 5.9 ± 1.4 mm at surgery, 9.7 ± 1.1 mm at second surgery after 4–6 months, and 8.3 ± 1.8 at the follow-up at 8.5 ± 2.8 years (from 5 to 13 years). The implant stability registered was 73.2 ± 6.2 ISQ at the surgery and 75.8 ± 3.9 at the second surgery after 4–6 months. Conclusions. The present long-term follow-up study showed that the crestal approach for sinus floor bone augmentation without additional bone grafting results in predicable bone formation and high implant survival. The osteotome technique is a valid alternative to the more invasive lateral window technique in single cases with a minimum of 4 mm of VBH below the maxillary sinus.

Congenital Pseudoarthrosis of the Tibia (CPT) is a rare condition with a reputation for recurrent fractures and failure to achieve union. A large variety of surgical procedures have been attempted for the treatment of fractured cases of CPT with an average rate of union without refracture of only 50%. Intentional cross-union between the tibia and fibula has been reported to improve these results to 100% union with no refractures. This is a retrospective study of 39 cases of CPT in 36 patients treated by the Paley cross-union protocol with internal fixation, bone grafting, zoledronic acid infusion and bone morphogenic protein 2 (BMP2) insertion. All 39 cases of CPT united at the tibia and developed a cross-union to the fibula. Two patients had a persistent fibular pseudarthrosis, one that was later treated at the time of planned rod exchange and one that has remained asymptomatic. There were few postoperative complications. There were no refractures during the up to 7-year follow-up period. The most common problem was the Fassier-Duval (FD) rod pulling through the proximal or distal physis into the metaphysis (66.7%). This did not negatively affect the results and was remedied at the time of the planned rod exchange. The Paley Cross-Union Protocol is very technically demanding, but the results have radically changed the prognosis of this once sinister disease.

Short Implant

Compared to previous generations when tooth loss was common, modern dentistry has made it possible for people to keep their teeth healthy and attractive for their entire lives. Today, dental implants can replace missing teeth. Although the concept of a tooth implant is not new, advances in technology have improved the treatment process and the longevity of implants. Dental implants can be used for single tooth replacements, support for a permanent bridge, or as attachments to anchor a full denture securely to the jaw. The clinical reality is that many potential implant patients have limited bone height. When placing longer implants, the maxillary sinus and inferior alveolar nerve often present risk. Although bone grafting sinus lifts procedures help alleviate this risk, patients may still avoid treatment because of the financial costs and time for grafting procedures. Additionally, bone grafting procedures have their own inherent risks and morbidities which patients often find unacceptable. While Short Implants afford simpler and consistently more predictable treatments, which can significantly increase a patient’s acceptance of implant treatment. With the use of Short Implants, patients with limited bone height can often avoid the inherent risks and costs associated with bone grafting procedures. Additionally, the extended healing time and cost of bone grafting procedures are eliminated. This article describes a simple approach for placement of short implant in maxillary premolar and its subsequent restoration.DOI: http://dx.doi.org/10.3329/birdem.v2i2.12327(Birdem Med J 2012; 2(2):116-120)

A double-threaded compression screw (Herbert®) was used as internal fixation of metatarsal neck osteotomy and nonunion repair in 16 patients (18 feet). Fifteen patients had associated symptomatic conditions of the foot. Twelve patients had one or more previous surgical procedures on the involved foot. Fourteen patients (15 feet) underwent 20 primary or revision lesser metatarsal osteotomies. Four of these patients had undergone previous lesser metatarsal osteotomies and had developed recurrent pain beneath six metatarsals and transfer metatarsalgia in one case. The remaining two patients (three feet), with six nonunions from previous metatarsal osteotomies, had repair with screw fixation and bone grafting. Follow-up for the series averaged 14 months.

Objective: To identify factors of oral health important for the final outcome, after secondary alveolar bone grafting in patients born with unilateral cleft lip and palate and compare occlusal radiographs with cone beam computed tomography (CBCT) in assessment of alveolar bone height. Design: Observational follow-up study. Setting: Cleft Lip and Palate Team, Craniofacial Center, Uppsala University Hospital, Sweden. Patients: 40 nonsyndromic, Caucasian patients with unilateral complete cleft lip and palate. Interventions: Clinical examination, CBCT, and occlusal radiographs. Main Outcome Measurements: Alveolar bone height was evaluated according to Bergland index at a 20-year follow-up. Results: The alveolar bone height in the cleft area was significantly reduced compared to a previously reported 10-year follow-up in the same cohort by total ( P = .045) and by subgroup with dental restoration ( P = .0078). This was positively correlated with the gingival bleeding index (GBI) ( r = 0.51, P = .0008) and presence of dental restorations in the cleft area ( r = 0.45, P = .0170). There was no difference in the Bergland index generated from scoring the alveolar bone height on occlusal radiographs as with the equivalent index on CBCT. Conclusion: Patients rehabilitated with complex dental restoration seems to be at higher risk for progression of bone loss in the cleft area. Supportive periodontal therapy should be implemented after complex dental restorations in cleft patients. Conventional occlusal radiographs provide an adequate image for evaluating postoperative bone height in clinical follow-up.

Objectives: The choice of surgical options for traumatic anterior shoulder instability with severe glenoid bony defect remains controversial. The purpose of this study was to evaluate the outcomes after arthroscopic (AS) iliac grafting with capsulolabral reconstruction with a minimum of five-year follow-up. Methods: Subjects consisted of 24 patients (24 shoulders), including 22 males and 2 females, who underwent AS iliac bone grafting and were followed for more than five years. Eighteen shoulders were primary surgery, and 6 were revision surgery. The mean age at surgery was 30 years (range, 18-52), and the mean follow-up was 8 years (range, 5-11). The mean glenoid bony defect measured on preoperative 3D-CT was 22% (range, 20-28). All surgeries were performed under general anesthesia. Free bone graft with approximately 2.0 cm length and 0.8 cm height was harvested from the iliac crest with the patients in the supine position, (Figure 1) and then the patient was placed in the beach chair position. The bone graft was inserted in the glenohumeral joint and arthroscopically fixed to the anterior glenoid using 2 cannulated screws followed by soft tissue Bankart repair using four anchors. (Figure 2 Gr: graft GL: glenoid) Functional outcomes including Rowe score, sports return, and ROM were evaluated. Radiographic findings including Samilson osteoarthritis (OA) grade and graft evaluation using 3D-CT at the final follow-up were also evaluated. Results: No patients experienced re-dislocation after surgery except one patient. All patients returned to their sports after surgery except for one patient who was not engaged in any sports. The mean Rowe score improved significantly from 19 (range, 5-40) to 95 (range, 70-100) (p<.0001). Postoperative forward flexion showed significant improvement: 157 (range, 110-180) to 170 (range, 150-180) degrees (p=.006), but no improvement in external rotation: 56 (range, 30- 85) to 56 (range, 30-70) degrees, and internal rotation: T8 (range, T5-L5) to T10 (range, T7-L5) level. OA change progressed in 8 shoulders (40%). 3DCT at the final follow-up demonstrated remodeling of the graft in 20 shoulders (88%) and absorption in 3 shoulders (12%).Failure case: A 23-year-old male experienced re-dislocation of the left shoulder during snowboarding five-year after the index surgery. Healed graft fracture and screw breakage were confirmed on 3DCT images (Figure 3). Conclusion: AS iliac bone grafting for traumatic anterior shoulder instability with significant glenoid bone loss yielded a satisfactory outcome with a minimum of five-year follow-up. Although this is technically demanding procedure, AS iliac bone grafting with capsulolabral reconstruction for shoulders with severe glenoid bone loss is an effective and practical procedure.

Complications after implantation are noted at different follow-up periods [5, 6, 28, 33, 36, 38, 43]. It is known that the frequency of implant rejection varies, on average, from 3% to 35%, and an unoccupied inflammatory process leads to the loss of a dental implant [12].Currently, the development of peri-implantitis is more studied. However, as a result of clinical cases, the development of the inflammatory process from 6 months to 3 years after implantation was revealed. It has been established that during surgical procedures it is necessary to carry out a complex of prophylactic measures that make it possible to prevent the possibilities of inflammation developing [32].Reasonable and clinical application of the treatment-and-prophylactic rehabilitation complex in patients, taking into account individual characteristics in each clinical case, is relevant. So, the task of developing and justifying a complex of therapeutic measures, which allows to obtain a large number of complications during dental implantation, is not only medical, but also social.
