Subcutaneous emphysema during surgical gingival depigmentation: a case report.

Background: Subcutaneous emphysema related to dental procedures is well documented in literature. It usually occurs during or within minutes to hours after dental treatment and can be easily diagnosed by the presence of crepitus on palpation. Although it is self-limiting, it can develop to potentially life-threatening complications.

Tomographic assessment of bone changes in atrophic maxilla treated by split-crest technique and dental implants with platelet-rich fibrin and NanoBone versus platelet-rich fibrin alone: Randomized controlled trial.

Background: This study evaluated the clinical benefits of adding NanoBone with split-crest technique and simultaneous implant placement covered with platelet-rich fibrin membrane in horizontally deficient maxillary ridges in terms of crestal and horizontal bone changes and patient morbidity.

Methods: Forty patients indicated for maxillary ridge splitting and simultaneous implant placement were assigned randomly to the study groups: control group (Platelet Rich Fibrin membrane) and test group (Platelet Rich Fibrin membrane + Nanobone). The Cone Beam Computed Tomography Fusion technique was utilized to assess crestal and horizontal bone changes after five months of the surgical procedure.

Clinical Evaluation of the Coronally Advanced Lingual Flap Technique for Maintaining Primary Wound Closure Over Titanium Mesh After Guided Bone Regeneration: A Randomized Control Trial.

Purpose: To evaluate the clinical efficacy of the coronally advanced lingual flap (CALF) technique in terms of the extent of lingual and buccal flap advancement, the maintenance of primary wound closure, and safety in comparison to buccal flap advancement alone during horizontal ridge augmentation in the posterior mandible.

Materials And Methods: A total of 14 patients were randomly allocated to two different groups: buccal flap advancement without the CALF technique (control), referred to as the NO-CALF group, and buccal flap advancement with the CALF technique (test), referred to as the CALF group. Wound healing was monitored weekly for the first 4 weeks, then at 2, 4, 6, and 9 months postoperatively for any soft tissue dehiscence (titanium mesh [TM] exposure) along the incision line.
