Chronic renal failure is a progressive disease characterized by a gradual destruction of nephrons and a consequent reduction of\nkidney function. End-stage renal disease (ESRD) necessitates renal replacement therapy as peritoneal dialysis, hemodialysis, or\ntransplantation. Patients affected by ESRD or in hemodialysis are at risk for developing a number of comorbidities including\nhypertension, anemia, risk of bleeding, susceptibility to infection, medication side effects, and oral manifestations associated with\nthe disease itself and with hemodialysis treatment. In this context, oral diseases represent a potential and preventable cause of poor\nhealth outcomes in people with ESRD due to their relation to infection, inflammation, and malnutrition. The aim of this article\nwas to review ESRD and hemodialysis-associated manifestations and to describe the dental operative protocols for patients\nawaiting kidney transplantation in light of the most recent literature....
Objectives. The aim of the study was to evaluate and compare digital and traditional prosthetic workflow for posterior maxillary\nrestorations supported by an upright and a distally tilted implant at 3-year follow-up. Materials and Methods. Twenty-four patients\nwere treated in the posterior maxilla with 24 immediately loaded axial and 24 distally tilted implants supporting 3-unit or 4-\nunit screw-retained prostheses. Three months after initial loading patients were randomly stratified into two groups: definitive\ntraditional impressions were carried out in the control group, while digital impressions were performed in the test group. The\nframework-implant connection accuracy was evaluated by means intraoral digital radiographs at 3, 6, 12, and 36 months of\nfollow-up examinations. Outcome considerations comprised implant and prosthetic survival and success rates,marginal bone level\nchanges, and required clinical time to take impressions. Results. A total of 24 patients received immediately loaded screw-retained\nprostheses supported by an upright and a distally tilted implant (total 48 implants). No implant dropouts occurred, showing an\noverall survival rate of 100% for both groups. None of the 24 fixed prostheses were lost during the observation period (prosthetic\nsurvival rate of 100%). No statistically significant differences in marginal bone loss were found between control and test groups.\nThe digital impression procedure required on average less clinical time than the conventional procedure. Conclusions. Clinical and\nradiologic results suggest that digital impression is a predictable procedure for posterior maxillary restorations supported by an\nupright and a distally tilted implant....
Aim. To evaluate, with three-dimensional analysis, the effectiveness of alveolar ridge preservation (ARP) after maxillary molar\nextraction in reducing alveolar bone resorption and maxillary sinus pneumatization when compared to unassisted socket healing.\nMethods. Patients were included in the study following inclusion criteria and underwent minimally traumatic maxillary molar\nextraction followed by ARP using synthetic nanohydroxyapatite (Fisiograft Bone, Ghimas, Italy) (test group) or unassisted socket\nhealing (control group). Cone-beamcomputerized tomographies (CBCT) were performed immediately after tooth extraction (T0)\nand 6 months postoperatively (T1). CBCTs were superimposed by using a specific software (Amira, Thermo Fisher Scientific, USA)\nand the following items were analyzed in both groups: (i) postextractive maxillary sinus floor expansion in coronal direction and\n(ii) postextractive alveolar bone dimensional changes (both vertical and horizontal). All data were tested for normality and equality\nof variance and subsequently analyzed by independent samples T-test andMannâ??Whitney test....
Background.Maintenance of hard tissue in the case of impacted thirdmolars (M3M)with close relationship to themandibular canal\nis still a surgical challenge which may be overcome using the inward fragmentation technique. Methods. A consecutive case series\nof 12 patients required the extraction of 13 impactedM3Mwith a close relationship to the inferior alveolar nerve (IAN).Via occlusal\nminiflaps,M3Mwere exposed occlusal under endoscopic vision and removed by inward fragmentation.All patients received socket\npreservation with resorbable in situ hardening TCP particles to reduce the risk of pocket formation at the second molar. Results.\nAll 13 sites healed uneventfully. Bone height was assessed using CBCT cross-sectional reformats pre- and 3 months postoperatively.\nThe bone height was reduced by 1.54 mm lingual (SD 0.88), 2.91 mm central (SD 0.93), and 2.08 mm buccal (SD 1.09). Differences\nwere significant at a 0.05% level. No tissue invagination at the extraction sites was observed. Conclusions. Major bone defects can\nbe avoided safely using inward fragmentation surgery. The self-hardening bone filler appears to enhance the mineralization of the\nintrabony defect....
Severe forms of attrition are frequently found in patients with no or insufficient posterior occlusal support. Management of such\npatients using fixed or removable prostheses is a complex procedure and is still a challenge for clinicians. The present clinical\nreport describes step by step full mouth rehabilitation of a patient with severely worn dentition using computer-aided design/\ncomputer-aided manufacturing- (CAD/CAM) generated wax patterns, milled zirconia frameworks, and fabrication of removable\npartial denture (RPD) abutments using a digital-conventional method. The results were satisfactory during 18 months of follow-up...
