Subperiosteal circumferential connective tissue graft for vertical implant soft tissue augmentation

Clinical Advances in Periodontics, EarlyView.
Abstract Background Vertical implant soft tissue augmentation is indicated to optimize esthetic outcomes in cases of peri‐implant soft tissue deficiency or dehiscence, particularly when the peri‐implant mucosa is exposed during a full smile. This manuscript describes the use of a subperiosteal circumferential connective tissue graft (SC CTG) for ...

The pedicle screw-rod system is an acceptable method of reconstructive surgery after resection of sacroiliac joint tumours [PDF]

, 2016
Hemipelvic resections for primary bone tumours require reconstruction to restore weight bearing along anatomic axes. However, reconstruction of the pelvic arch remains a major surgical challenge because of the high rate of associated complications.

Effect of Insertional Direction of Pedicle Screw on Screw Loosening: A Biomechanical Study on Synthetic Bone Vertebra under a Physiology‐like Load

Orthopaedic Surgery
Objectives It is now understood that pedicle screw loosening at the implant‐bone interface can lead to poor screw–bone interface purchase and decreased fixation stability. Previous biomechanical tests used cadaveric vertebrae and pull‐out or torque loads

Biologic gracilis augmentation with iliotibial band enhances recovery and lowers complications in ACL reconstruction compared with hamstring plus lateral tenodesis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare the iliotibial band autograft biologically augmented with gracilis (ITBAG) technique with a hamstring tendon autograft combined with extra‐articular lateral tenodesis using fascia lata (HT‐LET), in terms of (1) return‐to‐sport rates, (2) patient‐reported functional outcomes and (3) complication rates.

Analysis of CT-based navigation system for pedicle screw placement

, 2013
The incidence of pedicle screw breech varies based on anatomic location, body habitus, surgeon experience, spinal deformity, and surgical technique. Pedicle breeches have been reported to occur in up to 40% of screws.

What is the Effect of Pedicle Screw Reinsertion Through the Same Trajectory on Pullout Strength?

, 2021
AIM: To investigate the pullout strength of a pedicle screw reinserted through the same trajectory MATERIAL and METHODS: Fifty freshly frozen lamb L4 vertebrae were divided into the following five groups: Group 1, inserted with a 5-mm pedicle screw ...

Three‐Dimensional Scaffolds for Bone, Soft Tissue, and Periodontal Regeneration

Journal of Periodontal Research, EarlyView.
Three‐dimensional scaffolds offer tissue‐specific control of architecture, mechanics, porosity, and functionalisation to improve bone, soft tissue, and periodontal regeneration. ABSTRACT The oral cavity presents three distinct regenerative challenges: restoration of alveolar bone volume and stability, augmentation of soft mucogingival tissues, and ...
