Seventy-two sintered titanium fiber composite implants were placed subperiosteally and anchored intraosseously on the lateral aspect of 12 dog mandibles. The implants were covered with either Millipore filter, silicone, or left uncovered. Analysis after the animals were killed showed that bone growth into the subperiosteal portion of the implants was maximal at three to six weeks after implantation and remained at a depth of 380 mu through 24 weeks in a majority of the implants. Bone growth into the intraosseous portion also peaked at three to six weeks and remained at 190 to 380 mu through 24 weeks. Covering the implants slowed the rate of osseous ingrowth but did not affect the depth. The implants were well tolerated and the material holds promise for use in oral and maxillofacial surgery.
72枚烧结钛纤维复合种植体被置于12只犬下颌骨外侧的骨膜下并通过骨内固定。种植体分别用微孔滤膜、硅胶覆盖或不覆盖。处死动物后的分析表明，植入后3至6周，种植体骨膜下部分的骨生长达到最大值，并且在大多数种植体中，至24周时骨生长深度仍保持在380μm。骨内向骨内部分的生长也在3至6周达到峰值，至24周时保持在190至380μm。覆盖种植体会减缓骨向内生长的速度，但不影响生长深度。种植体耐受性良好，该材料有望用于口腔颌面外科手术。
