8
在进行引导骨再生时,屏障膜的屏障功能可以持续多久?

临床专家估计,在进行引导骨再生时,屏障膜的屏障功能至少要持续到临时基质和编织骨形成。在多数病例中,屏障功能要持续7-14天。最佳的屏障功能就是持续保持密封性能直至伤口愈合——这一过程正常情况下约为2周。

研究证实,Geistlich Bio-Gide®与屏障时间更长的膜相比具有相当的骨再生性能,但是却可以显著减少伤口愈合过程中的并发症。1-3

Geistlich Bio-Gide® Perio
1
Does the membrane have to be secured with fixation screws or pins?
As Geistlich Bio-Gide® Perio adheres very well to the defect, it is normally not necessary to utilize fixation screws or pins. However, fixation is possible if required.
2
Can Geistlich Bio-Gide® Perio be re-sterilized?
No. Autoclaving or hot-air sterilization irreversibly destroys the collagen structure. The physical properties of the membrane are changed and the consistency of the product becomes like parchment paper. In addition the product is not approved for re-sterilization and therefore may not be used.
3
What happens if the membrane is applied with the rough surface towards the soft tissue?
The bilayer structure of Geistlich BioGide® Perio has a compact and porous surface. The compact layer of Geistlich Bio-Gide® Perio exhibits higher cell occlusiveness than the rough, porous layer, preventing the downgrowth of epithelial cells. If the membrane is applied with the porous surface placed toward the soft tissue, integration of the bone cells may take place more slowly. However, it is not necessary to remove the membrane.
4
Is it possible to have an allergic reaction to Geistlich Bio-Gide® Perio?
As Geistlich Bio-Gide® Perio is made of collagen, allergic and inflammatory tissue reactions cannot be excluded. However, this is extremely rare.
5
Have inflammatory reactions been associated with Geistlich Bio-Gide® Perio?
Inflammation is a possible complication, which may occur with any surgery. However, the biocompatibility of Geistlich Bio-Gide® Perio has been verified in clinical studies and the incidence of complications is low.
6
What is the difference between Geistlich Bio-Gide® Perio and Geistlich Bio-Gide®?
The surface of Geistlich Bio-Gide® Perio has been made firmer when dry to facilitate periodontal applications. Second, the outer blister pack of Geistlich Bio-Gide® Perio includes four sterile water repellent templates. These can be placed repeatedly in the region of the defect to allow customization of the template before trimming the membrane to the precise shape.
Geistlich Mucograft®
1
Are antibiotics needed after treatment with Geistlich Mucograft®?
After treatment with Geistlich Mucograft®, please follow the same postsurgical management that is usually applied with connective tissue grafts or free gingival grafts.
2
Should Geistlich Mucograft® be used submerged or in open healing situations?
It depends on the indication:
1. Gain of Keratinized Tissue:
Open healing is recommended when Geistlich Mucograft® is used to increase the width of keratinized tissue. The innovative design of Geistlich Mucograft® allows excellent healing in open healing situations1.
2. Recession Coverage: Geistlich Mucograft® should remain completely submerged under the flap to avoid premature resorption of the collagen.2-4 Direct blood supply is important.

3
Should Geistlich Mucograft® be placed directly over the bone or over the periosteum?
It depends on the indication:
1. Gain of keratinized tissue: Geistlich Mucograft® should be applied on a periosteal bed1,2 as direct blood supply is important. In open healing, the blood is supplied through the edges of the device from the surrounding tissue and from the periosteum.
2. Recession Coverage: Geistlich Mucograft® can be used partially or completely over bone.3-5 Blood is supplied through the edges of the device from the surrounding tissue and from the flap completely covering the matrix.

4
How many layers of Geistlich Mucograft® should be used?
In the majority of the clinical cases reported and in all the studies performed with Geistlich Mucograft®, one matrix layer was used. Presently, clinical data is not available to prove that several layers of the device outperform a single layer of Geistlich Mucograft®.
5
Which side of Geistlich Mucograft® should face the bone?
The compact structure should face,away from underlying bone, with the spongeous structure facing the bone or soft-tissue wound bed. No clinical or comparative data is available regarding the performance of Geistlich Mucograft® when placed with the compact structure facing the bone or soft-tissue wound bed.

6
What suture should be used with Geistlich Mucograft®?
Published data shows different suturing techniques with Geistlich Mucograft®: non-resorbable1,2 and resorbable3, 0-51,2 and 0-64. There is no clinical evidence showing a benefit of one type of suture over another one when suturing Geistlich Mucograft®.

Should Geistlich Mucograft® be handled/applied wet or dry?
Geistlich recommends handling and applying the material dry, as it is easy to trim and pre-suture.
10
Does Geistlich Mucograft® need to be treated prior to application to the defect?
Geistlich Mucograft® is ready to be applied directly to the defect and does not need treatment or hydration prior to application. Due to its excellent hydrophilicity, the matrix will hydrate quickly with the patient’s blood after placement in the defect.
11
Is Geistlich Mucograft® an alternative for free gingival graft (FGG) or for connective tissue graft (CTG)?
Geistlich Mucograft® can be used as an alternative to both a free gingival graft or a connective tissue graft (CTG) for increasing keratinized tissue1-3. Geistlich Mucograft® is also an alternative to CTG for use in recession coverage procedures4-6.

Geistlich Mucograft® Seal
1
What suture should be used with Geistlich Mucograft® Seal?
Geistlich Mucograft® Seal should be sutured using non-resorbable sutures, not glued1. The close adaptation of the device to tissue borders can be accomplished by single interrupted sutures, double interrupted sutures, cross sutures, or sling sutures1.
The finest possible suture material comfortably used by the surgeon should be selected: for single interrupted sutures, the 6.0 or 5.0 suture size is recommended; for cross-suturing, a 5.0 suture size is appropriate1.

References:
  1. Geistlich Mucograft Seal Advisory Board Meeting Report, 2013. Data on file Geistlich Pharma AG, Wolhusen, Switzerland.
2
Can Geistlich Mucograft® Seal be stretched?
No. Geistlich Mucograft® Seal shows a limited elongation and should always be sutured tension-free.
3
Which side of Geistlich Mucograft® Seal should face the bone?

The compact structure should face outward, away from underlying bone, with the spongeous structure facing the bone or soft-tissue wound bed. Geistlich Mucograft® Seal spongeous structure is striped for easier differentiation of the two sides. The striped spongeous structure should face the bone.

4
Does Geistlich Mucograft® Seal swell after implantation?
Our measurements indicate that the matrix does not swell further after hydration (90 minute period examined)1.

References:
  1. Data on file, Geistlich Pharma AG, Wolhusen, Switzerland
5
Should Geistlich Mucograft® be handled/applied wet or dry?
Geistlich recommends dry handling and application: Easy to trim, easy to pre-suture.
6
Does Geistlich Mucograft® Seal need pretreatment?
Geistlich Mucograft® Seal  is ready to be applied to seal the socket and does not need pretreatment or moisture before application. Due to its excellent hydrophilicity, the matrix will hydrate quickly after implantation in the defect by soaking rapidly the patient’s blood.
7
Is Geistlich Mucograft® Seal resorbable?
The collagen of Geistlich Mucograft® will be replaced by newly formed soft tissue. The matrix is rapidly vascularised and colonised by soft-tissue cells1,2. This leads to a good integration of the matrix without any signs of foreign body reaction3,4.

8
What is Geistlich Mucograft® Seal made of?
Geistlich Mucograft® Seal consists of porcine collagen and is specifically designed for soft-tissue regeneration. The matrix is built up of a compact structure that gives stability while allowing open healing, and a spongy structure that supports blood clot stabilisation and ingrowth of soft-tissue cells.
9
What is Geistlich Mucograft® Seal?
Geistlich Mucograft® Seal is a unique 3D-matrix designed specifically for soft-tissue regeneration in extraction sockets for ridge preservation.
10
Why should I use Geistlich Bio-Oss Collagen® with Geistlich Mucograft® Seal, if I plan to implant after 8-10 weeks?
Geistlich Mucograft® Seal needs the support of Geistlich Bio-Oss® Collagen underneath for a good ridge preservation of the soft and the hard tissues. After 8 weeks, the soft tissues are healed but the mixture of the blood clot, Geistlich Bio-Oss® Collagen and the newly forming bone is still soft. Nevertheless the implant can be drilled carefully into the socket and the remaining Geistlich Bio-Oss® Collagen will favour the volume preservation of the ridge.
11
Does Geistlich Mucograft® Seal take up blood and saline equally well?
The hydrophile properties of Geistlich Mucograft® Seal favour a rapid moistening of the device either with saline or with blood.
12
How long is the Geistlich Mucograft® Seal resorption time?
The resorption time of every biomaterial including Geistlich Mucograft® Seal depends on multiple factors: defect size, metabolism and general health of the patient, etc. On the other hand, to determine an average resorption time of Geistlich Mucograft® Seal in humans, biopsies would be needed of the healing soft tissues after tooth extraction at different time points. This procedure is obviously not ethical and thus the average resorption time cannot be measured. However, single histologies indicate that after 8 weeks Geistlich Mucograft® is completely integrated into the newly formed soft tissue. 
13
What’s the difference between collagen sponges made by other manufacturers and Geistlich Mucograft® Seal?
Geistlich Mucograft® Seal is specifically designed for soft-tissue regeneration1. The collagen of Geistlich Mucograft® is specially processed to favour immediate blood clot stabilisation. This leads to early vascularisation1,3, facilitates soft-tissue cell ingrowth2  and excellent integration of the 3D-matrix with surrounding tissues2,3.  In contrast to other collagen products in the market, Geistlich Mucograft® and Geistlich Mucograft® Seal are well scientifically documented and their clinical benefits are proven.

牙科治疗领域

拔牙后拔牙窝处理
1
Geistlich Mucograft® Seal 能否用于拔牙窝位点保存的开放愈合?如果可以,如何操作?
可以。Geistlich Mucograft® Seal是自体软组织移植的一种替代方法。Geistlich Mucograft® Seal在干燥状态下即可使用,不需要提前水化或冲洗。在放置Geistlich Mucograft® Seal前,需要对相邻软组织进行去上皮处理。去上皮处理后,上皮细胞就可以轻松的从软组织边缘爬行进入Geistlich Mucograft® Seal内部。

2
如果我计划在牙齿拔除后8-10周进行种植,为什么需要将Geistlich Bio-Oss® Collagen与Geistlich Mucograft® Seal联合使用?
Geistlich Mucograft® Seal 在使用时需要Geistlich Bio-Oss® Collagen在下方做为支撑,这样才能更好的保存软组织和硬组织。8周之后,软组织已经愈合,但是由血凝块、Geistlich Bio-Oss® Collagen和新生骨组成的混合物还是松软的。这时需要小心地将种植体植入拔牙窝中,而剩余的Geistlich Bio-Oss® Collagen对保存牙槽骨非常有利。
3
文献推荐在牙齿拔除后多长时间进行种植?
  • 情况一:拔除牙齿后同期种植(即刻种植)
  • 情况二:牙齿拔除后4-8周种植(早期种植)
  • 情况三:牙齿拔除后12-16周种植(延期种植)
  • 情况四:牙齿拔除16周后种植(晚期种植)1

使用盖氏生物材料能否再生束状骨?
不管使用何种治疗手段,束状骨在牙齿缺失或者拔除后都会吸收。束状骨不能再生,但是,Geistlich Bio-Oss®或者Geistlich Bio-Oss® Collagen可以补偿束状骨的吸收,替代束状骨发挥功能,支撑周围的组织。1,2

患者关心问题

口腔组织再生
1
骨缺损的原因有哪些?
骨缺损的原因有很多,如创伤或者细菌性牙菌斑引起的牙龈和骨组织炎症(牙周炎)。在牙齿拔除后,由于机械应力的缺失,牙槽脊的宽度和高度也会逐渐下降。
2
生物材料在植入口腔后发生了哪些变化?
Geistlich Bio-Oss® 在4-6个月后与新生骨交织在一起,并且参与到骨的自然改建过程之中。Geistlich Bio-Gide®具有屏障作用,会在数星期后自然分解。
3
盖氏生物材料成功的证据有哪些?

口腔科临床医生使用Geistlich Bio-Oss®和Geistlich Bio-Gide®超过20年,已经成为口腔骨再生领域的标准治疗方案,是在世界范围内被广泛使用的口腔组织再生生物材料。人们对Geistlich Bio-Oss®和Geistlich Bio-Gide®进行了广泛的研究,结果证实其具有优异的疗效和可靠的安全性,并且有大量关于远期临床成功的数据。

4
牙齿拔除后会发生什么?

牙齿拔除后的数周至数月内,牙槽骨会逐渐吸收。这会导致出现下列问题:

  • 美学缺陷:牙槽骨吸收后,表面的牙龈也会出现退缩,会导致可见的软组织缺损。
  • 卫生问题:固定桥下的硬组织和软组织退缩后,固定桥与组织间的缝隙增大,这会对清洁工作造成困难。
  • 发音障碍:硬组织和软组织退缩后,会在牙齿之间或者修复体下面出现空隙,这会影响发音。
  • 昂贵且复杂的后续治疗:骨组织缺损后需要修复,这就需要进行大范围的骨组织和软组织增量。

5
盖氏生物材料的生产制造有哪些标准?

严格筛选原材料,严格控制生产过程,使Geistlich Bio-Oss®和Geistlich Bio-Gide®能够达到最高级别的安全标准,并且具有高耐受性。

严格的生产标准包括:

  • 严格筛选Geistlich Bio-Oss®和Geistlich Bio-Gide®生产原材料,仅使用经严格检验过的骨组织和胶原
  • Geistlich Bio-Oss®生产过程包括长时间高温煅烧和各种有效的化学和物理处理方法
  • 独立的机构和政府部门定期对生产过程进行监督
  • 对终端产品进行严格消毒
  • 记录严格的质量保证体系
6
什么时候需要进行骨增量治疗?
  1. 植入种植体:如果剩余的牙槽骨不能为种植体提供足够的初期稳定性,就需要进行骨增量手术。
  2. 牙周炎:牙周疾病(细菌性牙菌斑)可以导致牙周的牙槽骨吸收,这时就需要进行骨增量以保护剩余的牙齿。
  3. 大面积骨损伤:大面积骨损伤会导致大面积骨缺损,需要进行骨重建。
7
什么是生物材料?
生物材料是能够与活体组织接触并能实现某种功能的无生命材料,可以来源于天然物质,也可以在实验室人工合成。应用于医疗领域时,生物材料可以植入体内从而替代或者修复某些缺损的组织。
