Subsequent to dental extraction, residual ridge resorption manifests as an inherent biological process unfolding over an approximate duration of one year. This intrinsic phenomenon entails a substantial diminution, occasionally reaching 50%, in the initial bucco-lingual dimensions of the mandibular bone. To address this issue, a dental procedure known as the two-stage ridge split intervention is employed. This process involves two distinct stages: ridge splitting and extension. In the first stage, the dentist splits the alveolar crest to create a widening gap. This allows for the subsequent placement of dental implants. The splitting process is carefully executed to ensure that there's enough space for the implants to be securely embedded, and in the second stage, the widened gap generated through the split and extension of the alveolar crest is replenished with a suitable material. Two common options are hydroxyapatite, a synthetic bone-like substance that promotes bone regeneration, or autogenous bone grafts, which are harvested from the patient's bone, often from another site within the mouth. Following this two-stage procedure, the next step is to place dental implants. However, there's typically a waiting period of eight to 12 weeks. This interval allows for proper healing and integration of the grafted or filled material with the existing bone before the implants are installed. In this case report, a specific patient's experience with the two-stage ridge split procedure in the mandibular region is mentioned. Such case studies are valuable in assessing the success and viability of this dental intervention in narrow mandibular-width cases.
拔牙后,剩余牙槽嵴吸收表现为一种内在的生物学过程,大约持续一年时间。这种内在现象会使下颌骨最初的颊舌径大幅减小,有时可达50%。为解决这一问题,采用了一种名为两阶段牙槽嵴劈开术的牙科手术。这个过程包括两个不同阶段:牙槽嵴劈开和扩展。在第一阶段,牙医劈开牙槽嵴以形成一个增宽的间隙。这便于随后植入牙种植体。劈开过程需谨慎操作,以确保有足够空间将种植体牢固嵌入。在第二阶段,通过牙槽嵴劈开和扩展产生的增宽间隙用合适的材料填充。两种常见选择是羟基磷灰石,一种促进骨再生的合成骨样物质,或自体骨移植,即从患者的骨中获取,通常取自口腔内的另一个部位。经过这个两阶段手术,下一步是植入牙种植体。然而,通常需要八到十二周的等待期。这个间隔时间能使移植或填充的材料与现有骨充分愈合和融合,然后再安装种植体。在本病例报告中,提到了一位特定患者在下颌区域进行两阶段牙槽嵴劈开术的经历。此类病例研究对于评估这种牙科干预在窄下颌宽度病例中的成功率和可行性很有价值。
