The effect of implant diameter on osseointegration utilizing simplifi...
Jimbo, Ryo; Janal, Malvin N.; Marin, Charles; Giro, Gabriela; Tovar, Nick; Coelho, Paulo G. Journal article in Clinical Oral Implants Research;11 : Wiley (2014)	Journal article

English abstract:

Objectives: To observe and to compare histologically and histomorphometrically, the combined effect of drilling sequence and implant diameter in vivo. Material and Methods: A total of 72 alumina-blasted and acid-etched Ti-6Al-4V implants with three different diameters (3.75, 4.2, and 5 mm, n = 24 for each group) were placed in the right and left tibiae of 12 beagle dogs. Within the same diameter group, half of the implants were inserted after a simplified drilling procedure (pilot drill + final diameter drill) on one tibia and the other half were placed using the conventional drilling procedure on the other tibia. After 1 week, half of the animals (n = 6) were sacrificed, and the other half was sacrificed after 5 weeks (n = 6). The retrieved bone-implant samples were subjected to non-decalcified histologic sectioning, and the bone-to-implant contact (BIC) and the bone area fraction occupancy (BAFO) were analyzed. Primary statistical analysis used a mixed model analysis of variance with significance level set at P < 0.05. Results: Histologic observation showed that at 1 week, immature woven bone formed in vicinity of the implant, whereas at 5 weeks, the woven bone was replaced by lamellar bone, which formed in proximity with the implant. Histomorphometrically, the simplified technique was associated with significantly greater BIC and BAFO after 1 week. Differences between techniques were not longer apparent after 5 weeks, but BAFO was inversely and significantly associated with implant diameter at that time. Conclusions: The simplified technique did not impair either early or late bone formation for any tested implant diameter; however, wider diameters were associated with less bone formation at longer healing times for both techniques.

Historien som leder till sång - Ett utvecklingsarbete i förskolan om ...
Kron, Anette : Malmö universitet/Lärande och samhälle (2018)	Student essay 15hp

Swedish abstract:

Syftet med utvecklingsarbetet är att ur ett didaktiskt perspektiv undersöka och analysera ett sätt att arbeta med berättande som leder till musikproducerande. Arbetet, en kvalitativ studie med abduktiv ansats, synliggör barns läroprocess i relation till språkliga- och musikaliska aspekter. Berättande leder till en producerad sång som visar hur dessa aspekter kan samspela i olika uttryck. Ofta sjungs det redan producerade sånger på förskolan medan det är mindre vanligt att det produceras musik i förskolan. Teorin tar sin grund ur musikdidaktiken med begrepp som innehåll (linjärt och/eller icke-linjärt), aktivitetsformer (sång, spel och rörelse) och funktion (reproduktion och produktion). Utöver dessa centrala begrepp är literacy av vikt för utvecklingsarbetets analys, där det synliggörs hur barn samtalar i en samspelsdialog genom att vara delaktiga, involverade och autonoma. Genom barnens samspeldialog med ledaren återberättas historien om Sandvargen och Zackarina. Resultatet visar att barngruppen, utifrån en existerande berättelse, samspelar i en samspelsdialog där de utmanas språkligt när sångtexten produceras. Dramaturgin förstärks med rytminstrument i varierad dynamik. Resultatet visar att vid framträdandet samspelar ledare, barn, musik och historia.

Bone quality assessment in routine dental implant treatment among Bra...
Lindh, Christina; Oliveira, Guilherme Henrique C.; Leles, Claudio R.; Matias Freire, Maria do Carmo; Ribeiro-Rotta, Rejane F. Journal article in Clinical Oral Implants Research;9 : Wiley (2014)	Journal article

English abstract:

Objectives: To investigate the interpretation and assessment of bone quality among Brazilian and Swedish specialist performing implant treatment. Material and methods: A questionnaire was developed containing open and closed questions on attitudes, knowledge, and understanding of diagnostic methods for bone quality assessment. The questionnaire was sent by mail to dental implant specialists in Brazil while the Swedish version was Web-based and sent to specialists in periodontology and maxillofacial surgery. The response rate in the Brazilian group was 15.4% and in the Swedish group 36.5%. Results: Most respondents in both groups considered bone quality to be an important parameter for implant treatment outcome. Among Swedish specialists, bone quality, however, was considered to be of low relevance. The most popular method for assessing bone quality among Swedish specialists was the hand-felt perception of drilling resistance followed by radiography. The Brazilian specialists more often used peak insertion torque. Most respondents classified bone quality, and both groups used the classification proposed by Lekholm & Zarb (Tissue-Integratedprosthesis: Osseointegration in Clinical Dentistry, 1985, Quintessence, Chicago) most frequently. Conclusion: Specialists in both countries considered bone quality to be an important parameter for implant treatment outcome, but there was no consensus neither on what bone quality means nor on how to assess bone quality.

Osseointegration of metallic devices : Current trends based on implan...
Coelho, Paulo G.; Jimbo, Ryo Review article in Archives of Biochemistry and Biophysics; : Elsevier (2014)	Review article

English abstract:

Osseointegration of metallic devices has been one of the most successful treatments in rehabilitative dentistry and medicine over the past five decades. While highly successful, the quest for designing surgical instrumentation and associated implantable devices that hastens osseointegration has been perpetual and has often been approached as single variable preclinical investigations. The present manuscript presents how the interplay between surgical instrumentation and device macrogeometry not only plays a key role on both early and delayed stages of osseointegration, but may also be key in how efficient smaller length scale designing (at the micrometer and nanometer scale levels) may be in hastening early stages of osseointegration.

Cooper, Lyndon F.; Reside, Glenn J.; Raes, Filiep; Soliva Garriga, Joan; Giner Tarrida, Luis; Wiltfang, Jörg; Kern, Matthias; De Bruyn, Hugo Journal article in International Journal of Oral and Maxillofacial Implants;3 : Quintessence (2014)	Journal article

English abstract:

Purpose: This 5-year prospective multicenter study compared implant survival and success, peri-implant health and soft tissue responses, crestal bone level stability, and complication rates following immediate loading of single OsseoSpeed implants placed in anterior maxillary healed ridges or extraction sockets. Materials and Methods: Individuals requiring anterior tooth replacement with single implants were treated and immediately provisionalized. Definitive all-ceramic crowns were placed at 12 weeks. Implant survival, bone levels, soft tissue levels, and peri-implant health were monitored for 5 years. Results: One hundred thirteen patients received implants in fresh sockets (55) and healed ridges (58). After 5 years, 45 and 49 patients remained for evaluation, respectively. During the first year, three implants failed in the extraction socket group (94.6% survival) and one implant failed in the healed ridge group (98.3% survival); this difference was not significant. No further implant failures were recorded. After 5 years, the interproximal crestal bone levels were located a mean of 0.43 +/- 0.63 mm and 0.38 +/- 0.62 mm from the reference points of implants in sockets and healed ridges (not a significant difference). In both groups, papillae increased over time and peri-implant mucosal zenith positions were stable from the time of definitive crown placement in sockets and healed ridges. Compared to flap surgery for implants in healed ridges, flapless surgery resulted in increased peri-implant mucosal tissue dimension (average, 0.78 +/- 1.34 mm vs 0.19 +/- 0.79 mm). Conclusion: After 5 years, the bone and soft tissue parameters that characterize implant success and contribute to dental implant esthetics were similar following the immediate provisionalization of implants in sockets and healed ridges. The overall tissue responses and reported implant survival support the immediate provisionalization of dental implants in situations involving healed ridges and, under ideal circumstances, extraction sockets.
