An alternative approach was used to increase the buccal vestibular depth of two edentulous patients, using free epithelialized palatal grafts. Two edentulous patients presented with shallow vestibules and inadequate keratinized tissue width in the mandibular anterior region. These sites were treated with vestibuloplasty followed by placement of an epithelialized palatal graft. In order to minimize graft movement and possible mechanical trauma to the area, the graft was covered with the buccal flap during the initial stages of healing. The patients maintained an increase in the vestibular depth as well as the keratinized tissue width at 14 months and 5 years postoperatively. Successful outcomes in terms of increase in vestibular depth can be achieved with the use of epithelialized palatal graft that is covered during the initial stage of healing. The dental practitioner fabricating the complete denture should be aware of the advantages offered by this alternative surgical technique.
采用一种替代方法，即使用游离带蒂腭黏膜瓣，增加了两名无牙患者的颊侧前庭深度。两名无牙患者下颌前部前庭浅且角化组织宽度不足。这些部位先进行前庭成形术，然后植入带蒂腭黏膜瓣。为尽量减少移植瓣移动及对该区域可能的机械损伤，在愈合初期用颊侧瓣覆盖移植瓣。术后14个月和5年时，患者前庭深度及角化组织宽度均增加。在愈合初期覆盖带蒂腭黏膜瓣，可成功增加前庭深度。制作全口义齿的牙科医生应了解这种替代手术技术的优势。
