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.

Suitable subjects who were in need of implant placement were randomised between two groups; Group-A (NA=23) received crestal implant placement. In Group-B (NB=23) a CTG harvested from the ...
Does the tumor thickness value of buccal squamous cell carcinomas, predict cervical nodal metastasis in clinically and radio-graphical neck negative (N0) thus sparing such patients unneces...
This study will compare two commonly used soft tissue grafting techniques (free gingival graft, FGG vs. connective tissue graft, CTG) to augment the soft tissue around dental implants with...
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...
This study evaluates the feasibility of endo-laparoscopic full-thickness resection with simple suturing technique which did not expose gastric mucosa to peritoneum (simple non-exposure EFT...
The aim of the work described here was to compare intra-oral and transcutaneous ultrasonography (US) scanning and to determine the normal values of buccal mucosa thickness and echogenicity. A total of...
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...
Middle ear physiology includes both sound pressure transmission and homeostasis of its static air pressure. Pressure gradients are continuously created by gas exchange over the middle ear mucosa as we...
When an oral mucosa graft (OMG) is not a viable option for urethroplasty, colonic mucosa grafts have served as a promising alternative since described by Igor A. Thyrmos in 1902. In previous studies, ...
Gastric heterotopia is defined as the presence of morphologically normal gastric tissue at a non-physiological site, coexisting with the original tissue. Although it is not uncommon to see it in the e...
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.

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.
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
