Traditional versus Laterally Extended Upper Blepharoplasty Skin Excisions: Objective and Patient-Reported Outcomes.

Background: Different skin excision shapes may result in different aesthetic outcomes after upper blepharoplasty.

Methods: Two skin-only excision shapes were evaluated objectively and subjectively in 28 matched patients with laterally extended skin excision (group A) or traditional elliptical skin excision (group B). The pretarsal show, lateral eyebrow height, amount of scarring (evaluated with the Patient and Observer Scar Assessment Scale), and patient-reported aesthetic results (evaluated using FACE-Q) were scored and compared at 6 and 12 months postoperatively.

Incorporation of anterior iliac crest or calvarial bone grafts in reconstructed atrophied maxillae: A randomized clinical trial with histomorphometric and micro-CT analyses.

Background: Autologous bone grafts have been applied successfully to severely atrophied maxilla via a preimplant procedure. Differences in graft incorporation at the microscopic level can be the decisive factor in the choice between anterior iliac crest and calvarial bone.

Purpose: To compare conversion of anterior iliac crest bone and calvarial bone 4 months after grafting of the edentulous maxilla.

Calvarial bone grafts to augment the alveolar process in partially dentate patients: a prospective case series.

Background: Calvarial bone grafts as a pre-implant augmentation procedure are mostly used to reconstruct the edentulous maxilla, although calvarial grafts could also be used in the partially dentate patients needing extensive bone grafting.

Methods: In 7 consecutive partially dentate patients needing bone grafting because of a large bony defect as a result of trauma (n = 1), oligodontia (n = 1), failed previous bone augmentation (n = 1), or atrophy (n = 4), the alveolar process was reconstructed with calvarial bone as a pre-implant procedure.

Results: A total of 30 implants was placed either immediate at the time of bone grafting (13 implants) or after a healing time of 4 months when immediate placement was not possible (17 implants).

Histomorphometric and micro-CT analyses of calvarial bone grafts used to reconstruct the extremely atrophied maxilla.

Background: Calvarial bone grafts are successful in the reconstruction of the severely atrophied maxilla as a pre-implant procedure. However, not much is known about graft incorporation at the microscopic level.

Purpose: This study aimed to assess calvarial bone conversion 4 months after being grafted in the edentulous maxillary bone.

Patients' appreciation of pre-implant augmentation of the severely resorbed maxilla with calvarial or anterior iliac crest bone:a randomized controlled trial.

Background: Little is known about the impact of bone graft harvesting for pre-implant augmentation of the maxilla from a patient's perspective. To assess patient-reported outcome measures (PROMs) related to augmentation of the extremely resorbed edentulous maxilla with calvarial or anterior iliac crest bone.

Materials And Methods: For this randomised controlled trial, 20 consecutive edentulous patients needing extensive pre-implant surgery of the maxilla were randomly assigned to either calvarial (n = 10) or anterior iliac crest (n = 10) bone harvesting.

Immediate dental implant placement in calvarial bone grafts to rehabilitate the severely resorbed edentulous maxilla: A prospective pilot study.

Purpose: The aim of this study was to describe the surgical technique of immediate dental implant placement in calvarial grafts for augmentation of the severely resorbed maxilla and to assess the treatment results.

Methods: In 13 patients the maxilla was augmented with calvarial bone followed by simultaneous dental implant placement (total: 68 implants). In the frontal "knife edge" region, implants were inserted in the buccal plated area.

Hyperbaric Oxygen Therapy for Wound Dehiscence After Intraoral Bone Grafting in the Nonirradiated Patient: A Case Series.

Purpose: In maxillofacial surgery, hyperbaric oxygen treatment is used almost exclusively as adjunctive therapy for osteoradionecrosis of the mandible in irradiated patients. It also is used to prevent the occurrence of osteoradionecrosis in the irradiated patient when dental surgery is indicated. Theoretically, hyperbaric oxygen therapy should benefit the nonirradiated patient in maxillofacial surgery (eg, patients with persistent intraoral wound dehiscences after bone grafting).

Donor site morbidity of anterior iliac crest and calvarium bone grafts: A comparative case-control study.

Purpose: Notwithstanding its donor site morbidity, autogenous bone graft harvesting is still considered the gold standard for cases of extreme resorption of the alveolar ridge. The aim of this study was to assess donor site morbidity of calvarium and anterior iliac crest harvesting.

Material And Methods: A total of 27 edentulous patients who had undergone calvarial bone harvesting were matched with 27 edentulous patients in which anterior iliac crest bone was harvested.

[A woman with a painful mouth].

A 44-year old woman presented with a painful mouth. This pain was the result of prolonged inadequate dental hygiene. Extensive calculus formation was present on the molars next to the parotid oroficia.

Safe harvesting of outer table parietal bone grafts using an oscillating saw and a bone scraper: a refinement of technique for harvesting cortical and "cancellous"-like calvarial bone.

Calvarial bone is a readily available source of bone for preimplantation augmentation procedures of the alveolar process. However, the calvaria consist mostly of cortical bone, and cancellous bone of the diploic space is scarce. A bone scraper (Safescraper Twist; META, Reggio Emilia, Italy) was used to create a beveled trough around the calvarial outer table graft to facilitate its removal with an oscillating saw.

The influence of three barrier membranes on modeling and incorporation of autologous onlay bone grafts in rats. An evaluation by transversal microradiography.

Objectives: To determine whether covering an autologous bone grafts with three different barrier membranes prevents graft resorption, and to compare these membranes to each other.

Design: In 192 rats a standardised 4.0mm diameter bone graft was harvested from the right mandibular angle and transplanted to the left.

Vivosorb, Bio-Gide, and Gore-Tex as barrier membranes in rat mandibular defects: an evaluation by microradiography and micro-CT.

Objectives: The objectives of this study were to determine whether a new degradable synthetic barrier membrane (Vivosorb) composed of poly(dl-lactide-epsilon-caprolactone) (PDLLCL) can be useful in implant dentistry and to compare it with collagen and expanded polytetrafluoroethylene (ePTFE) membranes.

Material And Methods: In 192 male Sprague-Dawley rats, a standardized 5 mm circular defect was created through the right angle of the mandible. New bone formation was evaluated by post-mortem microradiography and micro-CT (muCT) imaging.

A comparison of micro-CT, microradiography and histomorphometry in bone research.

Objective: Intraobserver reliability and agreement were determined for microradiography (MR), micro-computed tomography (microCT) and histomorphometry (HM). These three modalities were compared for quantitative measurements of bone formation and graft modelling in rat mandibular defects and grafts.

Design: Twelve rats were randomly selected from a larger experiment, evaluating bone formation in rat mandibular defects and bone modelling in grafts.

Does platelet-rich plasma promote remodeling of autologous bone grafts used for augmentation of the maxillary sinus floor?

The aim of this study was to evaluate the effect of platelet-rich plasma (PRP) on remodeling of autologous bone grafts used for augmentation of the floor of the maxillary sinus. In five edentulous patients suffering from insufficient retention of their upper denture related to a severely resorbed maxilla, the floor of both maxillary sinus was augmented with an autologous bone graft from the iliac crest. Randomly, PRP was added to the bone graft used to augment the floor of the left or right sinus (split-mouth design).
