Immediate implant with socket shield and immediate implant without socket shield are the two techniques which can be used to preserve the already thin labial bone in the esthetic region, thus eliminating the need for graft materials.
To compare the efficacy of immediate implant placement after extraction without socket-shield technique and with socket-shield technique in the esthetic region.
Sixteen patients who reported with unsalvageable maxillary anterior teeth with labial bone thickness of less than 2 mm, depicted on preoperative CBCT, were chosen for the study and randomly assigned one of the two groups: Group A comprising socket-shield technique patients and Group B comprising immediate implant placement without socket shield. The labial bone thickness was analyzed along its entire length through CBCT scan at definite follow-up intervals up to a period of 12 months after the procedure.
Follow-up of 1 year demonstrated a statistically significant reduction in the labial bone thickness at the crest in Group B after 8th and 12th months of implant placement.
The two techniques need further comparison though our study results demonstrated better preservation of bone through the socket-shield technique, thus eliminating the need for any bony substitutes.
带牙槽窝屏障的即刻种植和不带牙槽窝屏障的即刻种植是两种可用于保留美学区域已很薄的唇侧骨的技术，从而无需使用植骨材料。
比较美学区域拔牙后不采用牙槽窝屏障技术和采用牙槽窝屏障技术即刻种植的效果。
选择16例术前CBCT显示上颌前牙唇侧骨厚度小于2mm且无法保留的患者进行研究，并随机分为两组：A组为采用牙槽窝屏障技术的患者，B组为不采用牙槽窝屏障的即刻种植患者。术后12个月内，在特定的随访间隔通过CBCT扫描分析唇侧骨全长的厚度。
1年的随访显示，B组在种植后第8个月和第12个月时，牙槽嵴顶唇侧骨厚度有统计学意义的降低。
尽管我们的研究结果表明牙槽窝屏障技术能更好地保留骨，从而无需任何骨替代物，但这两种技术仍需进一步比较。
