“…Facial soft tissue recession often occurs shortly after abutment connection/crown placement (Bengazi et al 1996, Small & Tarnow 2000, De Rouck et al 2008, but subsequently remains relatively stable during various observation periods (Adell et al 1986, Apse et al 1991, Jemt et al 1994, Bengazi et al 1996, Andersson et al 1998, Scheller et al 1998, Grunder 2000, Priest 2003, Cardaropoli et al 2006, Jemt et al 2006, Rompen et al 2007, De Rouck et al 2008. A thick mucosa (≥1 mm) at the mid-buccal aspect of implants was associated with less mucosal recession compared with a thin mucosa (<1 mm) (zigdon & Machtei 2008).…”

“…The connective tissue contacts the titanium implant or abutment, but this interaction does not induce apical migration of the epithelium. Rompen et al 2007 assumed that this contact would be better described as adhesion (Guy et al1993;Rompen et al 2007). It is suggested that the adhesion is sufficiently tight to preclude epithelial down-growth, which could induce bone resorption (Listegarten et al 1991).…”

Marginal bone and soft tissue behavior following platform switching abutment connection/disconnection -a dog model study PhD THESIS Célia Coutinho AlvesAutorización do Director / Tutor da Tese (RD 778/1998) RESUMENLa literatura científica parece indicar que la conexión/desconexión del pilar protésico puede provocar alteraciones en la inserción epitelial, causando sangrado y ulceración en el mismo. Esta ruptura mecánica se puede considerar como una herida abierta con la exposición del tejido conjuntivo, lo cual puede resultar en una respuesta inflamatoria y consecuentemente en migración apical epitelial.Esta tesis resume un trabajo de investigación experimental "in vivo" diseñado con el objetivo principal de evaluar histológicamente el comportamiento del tejido óseo marginal, cuando se manipula, repetidamente, el pilar de conexión en implantes "switching-platform" colocados en perros Beagle.El objetivo secundario del estudio fue evaluar el comportamiento marginal de tejido blando tanto histológicamente (anchura bilógica) como clínicamente (cambios en el margen de la encía), y radiográficamente el comportamiento marginal de tejido duro (nivel óseo marginal), variando sólo la estabilidad de la conexión del pilar durante el procedimiento estándar de colocación de implantes Straumann® Bone Level la y su rehabilitación protésica.Se seleccionaron seis perros Beagle adultos fueron seleccionados, y se extrajeron los pre-molares en las posiciones Pm3 y Pm4 del ambos lados izquierdo y derecho, dejando un período de cicatrización de 3 meses. En este momento, se colocaron 24 implantes (BL) (Straumann®, Basilea, Suiza) Ø 3.3 / 8 mm, dos en cada lado y en las regiones Pm3 y Pm4. En uno de los lados (grupo control), se colocaron 12 pilares de cicatrización cónicos Ø 3,6 mm, y en el otro lado (grupo teste) lado, se conectaron 12 pilares multibase Narrow CrossFit TM (NC) (Straumann®, Basilea, Suiza) en el momento de la cirugía de colocación de los implantes. En el grupo test, todos los procedimientos de prótesis se realizaron directamente al pilar multibase pilar sin desconectarlo, y en el grupo control, el pilar multibase se conectó / desconectó cinco veces (en las semanas 6/8/10/12/14) durante los procedimientos protésicos.Posteriormente se confeccionaron 12 puentes fijos metálicos y se atornillaron 14 semanas después de la colocación de los implantes. Una visita de higiene / control fue realizada seis meses después de la colocación de los implantes. Los animales fueran sacrificados a los 9 meses del estudio. Los parámetros clínicos y radiográ-ficos (peri-apicales) se registraron en cada visita. El análisis histométrico se realizó para los 24 implantes. La distancia desde el hombro del pilar multibase al primero contacto del implante con hueso (S-BIC) se definió como variable principal.

“…11 A narrow transmucosal design increases the length of the implant-tissue contact and provides a horizontal healing space for the connective tissue, which might reduce the height required for biological width and subsequently the marginal bone loss due to soft tissue adaptation. [11][12][13] According to Rompen et al, 13 in a pilot clinical study, a concave transmucosal profile in 2-part implants led to a better and more predictable soft tissue stability in the aesthetic zone compared to the previous published data on implants with a divergent transmucosal design.…”

“…Findings in the literature on other soft tissue penetrating devices, such as amputation prostheses, external fixators, and dental implants, indicate that soft tissue stability may be improved by the use of improved abutment materials (12Y15) and/or improved designs (16). Ideally, a percutaneous abutment should provide conditions for integration with the surrounding soft tissue, thus immobilizing the surgical flap, without having to remove viable soft tissue.…”

Objective: The protocol for bone-anchored hearing implants (e.g., Baha A ) surgery involves reduction of soft tissues around the abutment to minimize the risk of skin-related complications. It is hypothesized that good soft tissue outcomes may be achieved without performing skin reduction if improved abutment designs and/or materials are used that provide enhanced integration with surrounding soft tissues. The aim of the study was to investigate soft tissue response to different abutment designs/materials. Methods: Thirty-six Baha implants and abutments were inserted in the skull of six sheep without performing soft tissue reduction. Four different abutments were used: 1) standard Baha abutments, 2) hydroxyapatite-coated standard Baha abutments, 3) concave titanium abutments, and 4) hydroxyapatitecoated concave abutments. Healing times of 1, 2, and 4 weeks were used (2 animals per time point). Samples were analyzed using descriptive histology and morphometric measurements, and results were compared using Wilcoxon's signed-ranked test.Results: Histologic assessment showed healthy soft tissues around the abutments with limited or no signs of inflammation. Hydroxyapatite-coated abutments showed tight adherence with dermis and limited epidermal downgrowth and pocket formation. Weaker adherence, often associated with significant epidermal downgrowth and pocket formation, was noted for noncoated titanium abutments. The mean pocket depth for abutment types A, B, C, and D was 1.38, 0.42, 1.51, and 0.24 mm, respectively. The difference between C and D was statistically significant (p = 0.031). Conclusion:The results showed enhanced dermal adherence and reduced epidermal downgrowth and pocket formation for hydroxyapatite-coated abutments, with the most significant effect recorded for the hydroxyapatite-coated abutments with a concave shape.
