Fabrication of Removable Partial Dentures

You may recall my post some time ago about Removable Partial Denture Design. If not you can find it here. Now that the design is complete, it's time to fabricate the denture.

Here's the RPD Design
This, according to the Kennedy classification is a Class II modification II arch.


After an alginate impression is made of the arch from the dentoform, it is then poured up in plaster.
 Though not very visible, the design/outline of the RPD is made on the cast
Wax is placed to block out undercuts


A record base is then made of triad material following the outline that was made on the cast
It is then cured, which makes it hard


Wax is then added to the edentulous spaces until contact is made with the lower arch
Alu-wax is added to articulate the upper arch with the lower arch

upper cast with record base in place along with with alu-wax
to articulate the lower with the upper arch
Lower arch. You can see remnants of the alu-wax where articulation was made

Endodontics: Access Opening

We start endodontics this semester. So far we've been learning how to open a tooth and access the root canal. We were also introduced to some of the basic instruments of the trade as well as the type of burs used to access the canal.

All things sharp and pointy

Endo Access Kit
Burs used for accessing root canals

Here are some of the teeth that I've accessed so far. Some are missing since I turned them in for grading.

Open access on a canine

Open acess on pre-molar


Steps to follow for accessing the canal:

  •  High speed hand piece with EAD4 bur to enter through enamel and dentin;
  •  followed by the use of a slow speed hand piece with the EARC4 bur to access the root canal and plane the canal walls.
  •  At this point a broach can be used to remove pulpal tissue. 
  • Using high speed han piece again the EARC4 or even the XGATE can be used to shape the access opening with guidelines for the particular tooth you are working on, eg: triangular outline for a maxillary central incisor or Oval outline for a canine.
Sorry for the crappy photos.

Roller Coaster Ride

This week I started my second semester of my second year! Man, time is flying (though not fast enough). Of course, the further I matriculate into Dental School the more hectic my schedule gets. This semester I have a whopping 13, THIR-TEEN classes plus clinic rotations to keep me well occupied and on my toes. Classes this semester include:

  • Oral Pathology
  • Anesthesia & Minor Oral Surgery
  • Pediatric Dentistry
  • Removable Prosthodontics II
  • Fixed Prosthodontics II
  • Fixed Prosthodontics II Lab
  • Periodontics
  • Therapeutics

  • Oral & Maxillofacial Radiology
  • Treatment Planning
  • Dental Practice Readiness Course
  • Clinic Rotations
Add studying and sitting the NBDE 1 to the mix as well as my campus organization leadership responsibilities, conferences, seminars and research and we've got ourselves one ca-raazy semester.

Join me on this journey. Buckle up!


ASDOH's The Dental Anomalies

I got introduced the other day to Dentistry's First Music Band: The Dental Anomalies.
The Dental Anomalies, Nima Afsari and Mark Anthony Williams II, are second year dental students at The Arizona School of Dentistry and Oral Health (ASDOH). They started blending their passion for dentistry and music when they first met and created a whole album which illustrates what it is like to be a dental student. The Dental Anomalies enjoy melodic sounds and try to incorporate many genres into their music, such as rock, rap, pop and jazz. With the release of their first album, the future of dentistry and music looks promising.

Here's a sneak peak of their album with the song: Through My Loupes.




Mark and Nima are some talented folks. Other productions of theirs include commercials, entrances and small movies which can all be found on ASDOH's ASDA website, and if you liked their first single go ahead and support them, our fellow Dental Students -their entire album can be purchased from their blog here

Definitely a fun way to take away the stress of dental school

Removable Prosthodontics: Complete Dentures

Earlier, I made several posts about complete dentures and setting teeth. Since then, I've done a couple more and of course, with practice everything gets better.

1st Set-Up:

This was my very first set-up. Of course at the time I thought this was great
but looking back...yikes! You can clearly see that the left side is slightly higher
than the right, and the wax job is nothing to call home about.
Upper Arch
Looks a bit like it's leaning to the left an the 2nd molars are sticking out
too far bucally.
 Lower Arch:
Lots of faults: Right canine is making the distal turn, lingual gingiva on
the right too thin, left 1st premolar sticking too far bucally, etc etc

2nd Set -Up

Looks much better than the first, neater, more polished...
However, left posteriors sticking too far bucally.
 Upper Arch
Some areas needed wax re-enforcement.  2nd molars might have
been placed too far bucally.
 Lower Arch
Looks okay to me

 3rd Set-Up
Good, better, best right? In terms of occlusion, presentation, etc this one
turned out best.
 Complete dentures!
before festooning
 You can see here a little festooning and gingival anatomy

The Saga continues next semester. Stay tuned!

20 Questions with Dr. M. Rogers DDS (Ortho edition)

While perusing the Articles and Interviews section of the Student Doctor Network, I came across an interview with Orthodontist Dr. Michael Rogers who describes the field of Orthodontics and pinpoints the reasons he chose the field and why he thinks the field is  the best specialty.
Some points mentioned are note worthy if you are thinking of specializing in Orthodontocs.

The article/interview:

Dr. Michael B. Rogers owns a private orthodontics practice with his colleague Dr. Andrews in Augusta, Georgia. He graduated from Emory University School of Dentistry before serving as a Captain and general dentist in the U.S. Army Dental Corps. Later, he returned to the Medical College of Georgia to specialize in orthodontics, earning his Certificate in Orthodontics from the Georgia Health Sciences University (Medical College of Georgia) School of Dentistry.
Dr. Rogers is currently on the orthodontic faculty at the Georgia Health Sciences University and is a Diplomate of the American Board of Orthodontics. He has received numerous professional recognitions, including those from Georgia Association of Orthodontists (Exemplary Service Award, 1991 and 2006), Oren A. Oliver Southern Association of Orthodontists (Distinguished Service Award, 2002), and Emory University School of Dentistry (Meritorious Service Award, 2009).
Dr. Rogers has been active in several professional organizations, including the American Dental Association, Georgia Dental Association, American Association of Orthodontists, Southern Association of Orthodontists, Georgia Association of Orthodontists, Medical College of Georgia Orthodontic Alumni Association, Georgia Health Sciences University School of Dentistry Steering Committee, College of Diplomates of the American Board of Orthodontics, Eastern District Dental Society, and Georgia Academy of Dental Practice. He has been published in the Journal of Clinical Orthodontics, Orthodontic Products, and the American Journal of Orthodontics.
When did you first decide to become an orthodontist? Why?
When I was a sophomore in dental school, we had an orthodontic lab and I enjoyed the challenge of bending the wires. In addition, I began to realize how orthodontics can improve a person’s self esteem by improving their appearance. It can make a difference in the job offers they receive, and even their selection of a spouse.
How/why did you choose the school you attended?
I lived in Augusta and selected Emory University (in Atlanta). Its dental school had an excellent reputation. Emory was also the only dental school in Georgia, South Carolina, or Florida at that time. My orthodontic education was at the Georgia Health Sciences University, formerly the Medical College of Georgia.
What surprised you the most about your studies?
I was surprised in dental school by the amount of lab work and dexterity that were involved. Being “good with your hands” is very important for a successful dental career.
If you had it to do all over again, would you still become an orthodontist? (Why or why not? What would you have done instead?)
Yes, if I had it to do all over again, I would still become an orthodontist. Orthodontics has been a rewarding career from all aspects. It has allowed me to influence many lives through improving their smiles.
Has being an orthodontist met your expectations? Why?
Yes, being an orthodontist has more than met my expectations, because it has allowed me to influence many lives by improving their smiles. In orthodontics there are no failures since everyone experiences some improvement. It is very rewarding to see the big smile when the braces are removed, and in many instances the improvement in self esteem.
What do you like most about being an orthodontist?
As an orthodontist, I most enjoy dealing with people and the many variations in orthodontic cases. Some cases involve jaw surgery while others require functional appliances (growth appliances). In addition, I enjoy seeing the “big happy smile” at the end of treatment.
What do you like least about being an orthodontist?
Like any business that depends on appointment keeping, I am sometimes frustrated with the way the schedule can become hectic if patients are running late. On occasion, the schedule is delayed by patients whose appliances are loose and in need of repair. In addition, some patients will not brush their teeth or cooperate in other ways, which can lead to a lot of frustration. Patients can compromise the results of their treatment if they do not keep up with home hygiene, diet recommendations and professional prophylaxis.

Specialize or Not?

Earlier you might have seen me mention my interest in specialty, particularly Orthodontics or Oral & Maxillofacial Surgery (OMFS). While I find the OMFS procedures very interesting, whilst doing further research on the field, I have decided that the lifestyle that profession affords is definitely not for me.

So I'm back at the drawing board.


I'm still very interested in Orthodontics but since my debut in the Sim lab at the start of my 2nd year I think General Dentistry might be great after all (keep in mind I have not started seeing patients yet). I find myself asking this question a lot lately: Should I specialize or not? The answer to that question is not yet apparent but in the meantime I have decided to continue doing my research on the specialties and perhaps spend some time shadowing or assisting different specialists in hopes of arriving to an answer to my question.

When I figure it out you'll be the first to know.
