This study aimed to clinically evaluate the efficacy of vestibuloplasty around lower molar implants using 3 different modalities: apically positioned flap alone (APF), APF with a free gingival graft (FGG), and APF with modified periosteal fenestration (mPF).
Three different vestibuloplasty procedures during second-stage implant surgery were performed at the mandibular molar area in 61 patients with a shallow vestibule and insufficient keratinized tissue (KT). The clinical measurements of KT width were recorded at baseline, immediately after surgery (T0), 6 months after surgery (T6), and 12 months after surgery (T12). Soft tissue esthetic scores were measured.
An additional KT width gain from baseline to T12 of approximately 2 mm was obtained with FGG and mPF compared to that with APF. Shrinkage of the re-established tissue was lower with mPF and FGG than with APF, whereas the esthetic profile was better with APF and mPF than with FGG.
Within the limitations of this study, mPF showed potential as a promising approach for vestibuloplasty around the lower molar implants compared to the traditional APF and FGG.
本研究旨在通过三种不同方式对下颌磨牙种植体周围前庭成形术的疗效进行临床评估：单纯根尖定位瓣（APF）、带游离龈瓣的根尖定位瓣（FGG）以及带改良骨膜开窗的根尖定位瓣（mPF）。
在61例前庭浅且角化组织（KT）不足的患者下颌磨牙区进行二期种植手术时，实施三种不同的前庭成形术。在基线、术后即刻（T0）、术后6个月（T6）和术后12个月（T12）记录KT宽度的临床测量值。测量软组织美学评分。
与APF相比，FGG和mPF从基线到T12额外获得了约2mm的KT宽度增加。mPF和FGG重建组织的收缩率低于APF，而APF和mPF的美学效果优于FGG。
在本研究的局限性范围内，与传统的APF和FGG相比，mPF显示出作为下颌磨牙种植体周围前庭成形术的一种有前景方法的潜力。
