Influence of Mucosa Tissue Thickness on Marginal Bone Loss of Implants With Smooth Collars

2016-10-06 00:38:22 | BioPortfolio


The primary objective of this study is to compare the amount of implant marginal bone loss radiographically and probing depth in between thin and thick mucosa group that will receive a machined collar implant.

Null hypothesis is mucosa thickness does not affect implant marginal bone loss on implant with smooth collar.


Twenty eight adult patients who fulfill the inclusion criteria will be divided into 2 groups based upon the mucosa thickness (<2 mm and ≥2 mm). A signed written informed consent will be obtained from all subjects. Subjects will not be screened or treated until an informed consent has been obtained. Patient information will be protected according to the privacy regulations of the federal Health Insurance Portability and Accountability Act of 1996 (HIPAA).

The enrolled patients will receive implants with 1 mm polished collar. Implants will be restored at 4 (±1) months after placement. Outcome analyses will be performed until 1 (±1 month) year after loading and clinical and radiographic parameters will be evaluated to compare clinical outcomes between groups. The primary outcome is implant marginal bone loss and probing depth from clinical and radiographic measurements.

Clinical Evaluation of Vertical Inter-implant Papilla Height in Platform Matched Implants in Comparison to Morse Connection Abutments

The complete fill of the inter-implant mucosa is much more challenging between two implants, than single implants, and is considered to be unpredictable (Tymstra et al., 2011). However, pr...

Full thickness intraoral mucosa barrier models for in vitro drug permeation studies employing microneedles.

The use of permeation enhancers such as microneedles (MNs) to increase drug penetration across intraoral mucosa has increased in recent years. Permeation studies, commonly performed using vertical dif...

Rectal Mucosa Graft Take in Staged Urethroplasty.

Medical and Biotech [MESH] Definitions

A measurement of the thickness of the carotid artery walls. It is measured by B-mode ULTRASONOGRAPHY and is used as a surrogate marker for ATHEROSCLEROSIS.

A form of cutaneous tuberculosis. It is seen predominantly in women and typically involves the NASAL MUCOSA; BUCCAL MUCOSA; and conjunctival mucosa.

The measurement of subcutaneous fat located directly beneath the skin by grasping a fold of skin and subcutaneous fat between the thumb and forefinger and pulling it away from the underlying muscle tissue. The thickness of the double layer of skin and subcutaneous tissue is then read with a caliper. The five most frequently measured sites are the upper arm, below the scapula, above the hip bone, the abdomen, and the thigh. Its application is the determination of relative fatness, of changes in physical conditioning programs, and of the percentage of body fat in desirable body weight. (From McArdle, et al., Exercise Physiology, 2d ed, p496-8)

A prenatal ultrasonic measurement of the thickness or translucent area below the SKIN in the back of the fetal NECK, or nape of the neck, during the first 11-14 weeks of gestation (PREGNANCY TRIMESTER, FIRST). Abnormal thickness or nuchal translucent measurements resulting from fluid collection, is associated with increased risks of CHROMOSOME ABNORMALITIES. (Nicolaides et al., 1992)

Lining of the ORAL CAVITY, including mucosa on the GUMS; the PALATE; the LIP; the CHEEK; floor of the mouth; and other structures. The mucosa is generally a nonkeratinized stratified squamous EPITHELIUM covering muscle, bone, or glands but can show varying degree of keratinization at specific locations.
