Trauma of maxillary teeth is a common accident. In most cases, the result is a root or crown fracture requiring tooth extraction and implant placement. Immediate postextraction implants are considered an effective option for restoring missing teeth in order to achieve successful aesthetic and functional outcomes. The aim of this article is to describe a clinical case in which a fractured maxillary canine was replaced by an osseointegrated implant using a simplified technique in a patient who was a smoker and presented poor oral hygiene. The technique adopted permits a reduction of the number of implant components and consequently a lower cost of treatment, while at the same time maintaining acceptable aesthetic and functional outcomes.

“…This lesion might be more pronounced in the flap surgery group due to the larger wound surface, which allows for increased bacteria invasion. Furthermore, the enhanced reepithelization [12], reduced length of the junctional epithelium [7] and increased number of blood vessels [8] in the supracrestal connective tissue following flapless placement might provide a more effective barrier against bacterial invasion then in the flap surgery group.…”

“…You et al found significantly reduced height of the periimplant mucosa, length of the junctional epithelium, gingival index, bleeding on probing, probing depth and marginal bone loss 3 months after flapless placement as compared with flap surgery [7]. Furthermore, significantly more blood vessels were found in the supracrestal connective tissue 3 months after flapless insertion [8].…”

Analysis of inflammatory periimplant lesions during a 12-week period of undisturbed plaque accumulation—a comparison between flapless and flap surgery in the mini-pig

This study's aim was to clarify the influence of soft tissue management on the development of periimplant infection. Four weeks after removal of all maxillary premolars in 12 mini-pigs, four BEGO Semados RI implants were inserted in each maxillary quadrant. Employing a split-mouth design, one quadrant was randomized to flapless insertion while the contralateral side was chosen for flap surgery. Following 1, 2, 4 and 12 weeks of transmucosal implant, healing biopsies were retrieved from the periimplant soft tissue and subjected to further analysis. Histomorphometrically, a significant reduction of transmigration of polymorphonuclear neutrophils (week 1, p = 0.007; week 2, p = 0.021; week 4, p = 0.023; week 12, p = 0.013) as well as the density of the subepithelial inflammatory infiltrates (week 1, p = 0.007; week 2, p = 0.046; week 4, p = 0.003; week 12, p = 0.032) was verified following flapless surgery. Quantification of inducible nitric oxide synthase showed significantly reduced expression in the flapless group 2 (p = 0.027), 4 (p = 0.005) and 12 (p = 0.004) weeks post-insertion. Analysis of CD31 and collagen I immunostained sections revealed more regular capillary distribution as well as higher vessel and collagen density in the flapless group. The data of the present study indicate that flapless placement reduces the incidence of inflammatory periimplant soft tissue lesions during a 12-week period. Considering the beneficial effects of flapless placement on early soft tissue healing and stability, the technique might be preferred in case of an uncomplicated locoregional anatomy with sufficient hard and soft tissue. However, this positive effect might disappear after manipulation of the implant and soft tissue during impression taking or try in of the prosthodontic supraconstruction.

“…Although the pattern of bone loss around implants differs from teeth, as vertical bone "saucerization" is more implant-related feature, compared to horizontal resorption around teeth, an animal study by You et al 2009 showed that flapless implant placement resulted in significantly lower amounts of marginal bone loss.…”

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.
