@@valyamertarchyan9560 I add the contact stops to the caps to dissipate the occlusal forces under function. This will reduce any chance of stress fractures. Clients biting force is increased with no propreoception of force due to the elimination of perio ligaments in the edentulous state. Additionally the caps are cured to the frame and used in bite registrations and try-ins as a more secure position for those spots. And serves as a verification jig thus eliminating any surprises at the insertion appt. Thank you for your interest. Regards Paul

@@DentureAdventure Thank you for the explanation and your time.

Thanks for watching!

If only one endentulous free end then it would be categorized as a class II. See Class II design video

Thank you for your question and interest. I would follow the maxillary always for midline. I would maintain OJ in CO to minimize hyper occlusal contacts in function. I thought I maintained OJ in video. 1.2,1.3 to be extracted. Regards Paul

​@@DentureAdventure I apologize, it seems I'll need to watch the video again😊 (which I've already done twice because it's interesting). By the way, I've been spending 90% of my time on Denture Adventure instead of studying for exams. It is awesome✨! Thank you for your time and answers.

Thank you for your question and interest. This I would categorize as one of the most challenging for stability. Clasp posterior teeth as anterior and posterior as possible. Maintain minimum OB and OJ. Additionally major connector as far posterior as possible for indirect retention. Basically reverse class 1 in design. Regards Paul K

Thank you for your interest. Engaging the mesial undercuts would promote the retentive clasps to rotate into the undercuts. The reverse would provide no retention or no further retention as the rotation of the prosthetic would move these retentive clasps towards the tissue in theory. However by placing auxillary rests as you mentioned this would minimize the rotation. This value of rotation would be inherent on length of the guide planes, depth of undercut ,height of clinical crowns, type of antagonist dentition, alveolar bone height, type of saliva and occlusal scheme among others. This theory was based on studies by Prof.Dr. Markxor and is valuable in the education setting. Practically, I would see this type of endentulism treated with an acrylic partial denture foregoing any vertical stop which would exercise this theory for sure with a mesial buccal engaging wrought wire clasp anticipating this denture to be transitional in nature. Best of luck in your studies.

@@DentureAdventure Thank you for explaining. I will research studies by Dr. Markxor. Thank you for your time and information.

Maxillary or Mandibular? Many factors come into play.

This would depend on a few factors. Generally on a free end we would favor the mesial occlusal rest on the terminal abutment adjacent to the free end. If a tooth bound posterior modification exists we would favor the surface adjacent to the edentulous space. If an anterior modification is present, it would be prudent to close off these guide planes as well as all guide planes to food impaction. This would improve patient satisfaction and compliance in wearing removable prosthetics.

@@DentureAdventure thanks a lot

Thank you so much for the video Please why wasn’t RPI system used since it’s class 1 And I don’t understand why the last maxillary design is class 1 when it has just one free end

Hello Roshni Apron term would be synonymous with plating or full metal coverage of the lingual side of the teeth. Hope that helps !

So glad it helps! Best of luck in your studies.

hope you get a 10! 🥰

@@boglarka_d 💓

@@DentureAdventure thank you so much 😁 it really helped. The exam is a success.

My next testimony Amen

Good question ! I guess it would depend on the severity of the cross-bite. Classic would be 1st bicuspid class 1 with minimal overjet. 1st molar end to end in transition. 2nd molar cross-bite. Merci PK

DM me your email.

@@DentureAdventure Thank you so much Dr Paul. a very helpful videos! Happy Holidays!

I need the handouts worksheets for my exam tomorrow, is there a possible way you can send them to me?

Hi Juliette, Thank you for kind words. My hope is that we all take responsibility in designing our frameworks rather than letting a third party decide for us. For those that do, awesome. Continue being awesome practitioners. For those that don’t, never too late to start. PK

Thank you for your appreciation. Really just an average Dental Technician/Denturist trying to be better each day.

Your welcome ! Hope it helps.

Your most welcome. Hope it helps you and your patients as was the intention. Sincerely PK

Thank You for your question. The third design has a bilateral fee end. According the Applegate's rule #5 the posterior edentulous areas supercede the anterior edentulous space. Therefore in would be Kennedy class I modification 1. Hope that helps. PK

Where are you located ?

Thank you for your appreciation. Humbled to be categorized as best channel.

@@DentureAdventure you're welcome, but the appreciation is well deserved. I've been searching something like this channel for a long time as I'm still young(ish) and finding an informative gem like this, that covers all the various laboratory steps, from the surveying to the trimming, regarding this branch of the dental technology which fascinates me a lot, is uncommon over here on YT. And I searched a lot. I also like the name of the channel, which I consider spot on as watching these videos feels like watching a proper start to finish adventure, which is what our job, at last, is. My best regards, dear sir, keep up the good work. Greetings from Italy.

I can Lol. I may nod off.

Unusual ask ?

Your welcome ! Hope it helps !

Typical answer. It depends. Assuming the anterior edentulous is small and retention of posterior teeth is adequate indirect retention would most likely not be needed. If the space has a large width and flat vaulted palate with not so much posterior retention then a open palate design would help in minimizing rotations.

A edentulous space in the anterior segment that crosses the midline.

Glad you enjoyed it!

Glad it was helpful!

I assume vertically. Them metal occlusal. Sometimes it’s just too late for an Cast RPD!

@@DentureAdventure i have a case with less space mesiodistally any recommendations

You're welcome!

Hi Lule, Abutments for direct retainers are those teeth adjacent to the edentulous areas. Also could be categorized as primary abutments. If primary abutment teeth are guarded or compromised then prognosis would not be as favourable and possible secondary abutments utilized to anticipate possible future tooth loss. It would be better dentistry to address the health and longevity of abutments prior to treatment. Avoiding this I believe to be iatrogenic dentistry. Thank you for your comments.

Similar, however the rest is located off the reciprocal arm opposite of the guide plane.

Hi Hosein, I hope to post some design reflections and some examples in the near future.

Hi Anjali, guide planes and length of guide planes are important and indeed can be used to increase retention as well as below the survey line in the posterior without clasping as done routinely in transitional acrylic partial dentures. However long term use of such a prosthetic would be categorized as guarded at best do to no vertical support and vector pressures on all the natural dentition. This design obviously works but at what length of time and what cost to the periodontal health of the client. I think a more definitive fixed prosthodontic option would be favored such as bridgework and/ or implant supported therapy. I would refrain from mesial incisal rests and favor something on the lingual surfaces of laterals . Thank you for interest in prosthodontic discussions. Paul

Hello Anjali, Thank you for your interest in this channel. I will endeavor to include some unusual unorthodox treatment plan workflows in the near future. Regards Paul

Glad it helped

Hi Marium, Thanks you for your question. The design thoughts in the video are under the assumption that all the abutment teeth are sound with a good prognosis as well as plenty of room vertically. It is to highlighting best practices with an academic foundation. We should endeavor to locate mesial occlusal rests on terminal abutments with stress breaking clasp whenever possible. I bars, Y bars and W.W. clasps. departing from these clasps and rest position may compromise the life span of the abutments and reduce a positive prosthetic outcome. Taking this in consideration will help us create realistic treatment plans for our clients with a more definitive prognosis. Frenum location, alveolar height, degree and location of undercuts available, opposing dentition, previous and future restorative, vertical dimension, sulcus depth, length of guide planes, length of prosthetic occlusal table, depth of palate, quality and type of mucosa and saliva composition will guide us in design and appropriate treatment plans.
