Abstract:

In clinical practice, it is common to encounter dental implants with insufficient keratinized mucosa width (KMW) and decreased peri-implant mucosa thickness (MT). Research indicates that such soft-tissue deficiencies can lead to unsatisfactory esthetic results and decreased bone stability over time. This case report presents a variation of standard free gingival graft and connective tissue graft (CTG) techniques, termed the inverted partially epithelialized CTG (IPE-CTG). Three patients (2 males and 1 female) experiencing insufficient attached gingiva and reduced peri-implant tissue volume were effectively treated with the IPE-CTG. This approach involves placing a partially epithelialized graft as an onlay graft on the recipient site, with the epithelialized surface oriented apically and the de-epithelialized surface directed coronally. This technique aims to address KMW and MT deficiencies in a single procedure. All cases treated with the IPE-CTG exhibited stable results over a 12-month period, with notable improvements in both KMW and MT.

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Healing II: Complications

Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
