Anatomic factors influencing dimensions of soft tissue graft from the hard palate. A clinical study

Abstract

Objectives The aim of the present study was to measure the thickness of the palatal mucosa in a Jordanian (Middle Eastern) population as well as identify possible factors that may influence the thickness of palatal mucosa. Material and Methods Sixty period on tally healthy subjects (29 males and 31 females) were selected. Fifteen measurement points were defined on the palate. The mucosal thickness in the hard palate was determined by “bone sounding” with a Hu‐Friedy® round periodontal probe. Results The overall mean thickness of the palatal masticatory mucosa was 3.23 ± 0.47 mm.The mean thickness increased from the gingival margin to a more apical position irrespective of the tooth measured or side of the mouth in the following sequence: canine, second molar, first premolar, second premolar and lastly, the first molar. No significant difference between gender, smoking status, gingival phenotype andsides of the mouth with the thickness of palatal masticatory mucosa was determined. A significant difference between palatal shape and palatal gingival thickness was found. Conclusions The most appropriate site for graft harvesting is the canine‐premolar area 8‐13 mm from the mid‐palatal aspect of each respective tooth in a Jordanian population. Except for the palatal shape, the side of the mouth, smoking, gender or gingival phenotype does not affect the graft harvest. Clinical Relevance Scientific Rationale for Study Knowledge on the thickness of the masticatory mucosa is crucialin making decisions for surgical treatment modality and may affect surgical outcome. We measured the thickness of the palatal mucosa in a Jordanian population and identified possible influencing factors. Principal Findings The thickness varied according to the teeth and the canine to premolar region was found to be the appropriate donor site. Practical Implications This information on safe zone for graft harvest can guide the periodontist to make appropriate incisions and choose the appropriate location to obtain a graft of adequate thickness and dimensions.

Distal extension of palatal rugae as a limitation for donor soft tissue grafts in a Jordanian population: A cross-sectional study

“…The most appropriate area for graft harvesting is the canine-premolar area, 8–13 mm from the midpalatal aspect of each respective tooth. At this position, there less risk of endangering the greater palatine bundle but with an inherent risk of an aesthetic unacceptable outcome, particularly in free gingival grafts, due to the presence of the rugae [ 36 ].…”

“…Our findings revealed that 90.5% of the rugae reached the upper second premolar and 88.3% extended beyond its mesial aspect. So, basically, the rugae zone extended to the upper second premolar area which poses a problem, as the premolar area in the Jordanian population is the most appropriate donor graft area [ 36 ]. The problem is further complicated by the rugae extending as far back as the premolars, not only mesiodistally but also mediolateraly, indicating that it extended very close to the median palatine raphe posteriorly in most of the sample.…”

The Posterior Extension of the Palatal Rugae as an Anatomical Constraint for Soft Tissue Grafts in a Saudi Arabian Population

“…The preferred place to harvest grafts is from the canine-premolar region, 8-13 mm from the midpalatal face of each tooth [34]. The greater palatine bundle is less at risk in this location; however, the presence of the rugae increases the chance of an undesirable cosmetic result, especially with free gingival grafts [34]. There is not much information about the effect of transplanting tissue from the rugae-containing anterior palate.…”
