Treatment of peri-implant recession with a screw-retained, interim implant restoration: A clinical report.

This clinical report describes a patient with an osseointegrated implant and definitive restoration of the maxillary right lateral incisor who was seeking resolution of the recession of the peri-implant tissues which revealed the underlying zirconia abutment. The patient had previously received a connective tissue graft in an unsuccessful attempt to resolve the recession. An undercontoured interim restoration that allowed for soft tissue coronal migration resolved the soft tissue deficiency.

Avoiding a Vanilla Transhumeral Amputation.

Upper-extremity amputation, particularly at or proximal to the elbow joint, is devastating. The complexities of upper-extremity function are challenging to replicate, even with modern prostheses. This leads to a relatively higher rate of prosthesis rejection in upper-extremity amputees as compared to lower-extremity amputees. However, the challenges of performing a functionally useful transhumeral amputation should dissuade even the least of us from seeking to optimize both residual limb and patient functional potential. A poorly done, or even standard, transhumeral amputation is destined to d

Digital guides to facilitate retained root removal and simultaneous implant placement.

The aim of this study was to report the use of digital guides to locate impacted residual roots (IRR) (location guide) and to simultaneously insert dental implants (surgical guide). This case series included five patients. The IRR was first removed through a lateral window approach using the digital location guide, then the implant was placed simultaneously with the implant surgical guide. Definitive restorations were completed after a 6-month healing period. An average of 13.0 ± 3.1 minutes was required to locate the IRR. The implant stability quotient (ISQ) was obtained during surgery and be

Hydroxyapatite: an alternative method of frontal sinus obliteration.

Obliteration of the frontal sinus may be necessary for the treatment of chronic sinusitis, infectious complications, trauma, and benign and malignant neoplasms. Hydroxyapatite cement (HAC) is a relatively new material that is approved for the repair of cranial defects. HAC has been successfully used to obliterate the frontal sinus in 19 patients with few minor complications and the avoidance of donor site morbidity. Compared with other alloplastic materials, HAC has the advantages of easy use, biocompatibility, and osseointegration.

Balancing the Antibacterial and Pro-osteogenic Properties of Ti-Based Implants by Optimizing the Fluorination/Oxidation Level of Nanostructured Fluoride-Doped Hybrid Tantalum Oxide.

The two main problems with titanium implants are bacterial infection and insufficient osseointegration. The balance between osteoinductivity and antibacterial activity remains a formidable challenge because toxicity is usually introduced with enhancement of the antibacterial ability. In this research, a nanostructured fluoride-doped hybrid tantalum oxide (TaFO) was prepared on titanium by plasma-based surface modification. By a change of the fluorine-oxygen ratio, the fluorination/oxidation (F/O) level was optimized, and the dual effects of antibacterial activity and osteogenic promotion were …

Effects of Acetabular Screws on the Initial Stability of Porous Coated Acetabular Implants in Revision Total Hip Arthroplasty.

INTRODUCTION: Revision total hip arthroplasty in the setting of acetabular bone loss remains a challenging clinical entity. Deficiencies of the acetabular rim, walls, and/or columns may limit the bony surface area and initial acetabular construct stability necessary for osseointegration of cementless components. Press-fit acetabular components with supplemental acetabular screw fixation represent a common technique aimed to minimize implant micromotion and allow for definitive osseointegration. Although acetabular screw fixation is commonly practiced in revision hip arthroplasty, few studies t…
